The sofa armrest is at a height of 445 mm, and the tabletop has already been purchased with a thickness of 40 mm: is it worth buying wooden furniture legs MN-111 with a height of 390 mm if the coffee table should slide under the sofa

The most useful check in this project takes less than a minute. The tabletop is placed on temporary supports so that its top is at approximately the 430 mm mark, moved up to the sofa, and they try to slide it into the place where the coffee table will eventually stand. At this moment, the paper "15 mm of clearance" stops looking convincing: the armrest is soft, the floor is not perfect, the table does not move in a straight line, and its edge must pass under the sofa without touching and without the need to catch the right angle every time.

That is why you should not start here by choosing oak, "Prestige," or hardware. First, you need to answer one practical question: does the finished table actually fit under the sofa, or does it only seem suitable in arithmetic?

The nominal calculation is simple:

390 mm MN-111 + 40 mm tabletop = 430 mm.

The armrest is measured at a height of 445 mm:

445 − 430 = 15 mm.

On paper, the table fits. In a real room, 15 mm is just a preliminary margin until the actual tabletop thickness, leg attachment method, foot pad, finished floor, armrest softness, edge protrusion, and the actual trajectory along which the table will be slid are checked.

Therefore, it makes sense to buy four MN-111 legs not after the thought "430 is less than 445," but after a full-size height test. The good news is that for this check, you don't even need to first buy one expensive leg: the shape can be set aside, and the 430 mm height can be reproduced with boxes, blocks, or another stable temporary base.

MN-111 390×82×68 mm: first, let's confirm what exactly we are buying

The geometric furniture leg MN-111 has dimensions of 390×82×68 mm. In our scenario, the first parameter is critical—the height of 390 mm. It is this that is included in the vertical dimensional chain of the coffee table.

At the time of the final recheck, the card shows the following options:

The card also indicates enamel undercoating in the base configuration and an average production time of 5–10 days for custom orders. For mounting and hardware, FUR-001-1, FUR-044, FUR-012, and FUR-023 are recommended. This does not mean that all four items must necessarily be present simultaneously in a specific table: the structural assembly is selected separately.

Once the height and assembly scheme are confirmed, you can buy furniture legs MN-111 not "on a trial basis" anymore, but as four identical supports according to one specification.

Why B=82 and D=68 mm are secondary now

The dimensions of 82 and 68 mm are important for the seating area, leg proportions, distance to the tabletop edge, and fasteners. But they do not answer the main question of this article — whether the table will fit under the 445 mm armrest.

If you mix up priorities and spend a long time discussing the leg shape before checking the final height, you can choose an ideal visual option that physically does not perform the required function.

It is easy to buy table legs; it is harder not to make a mistake in the finished height

Category legs for a table to buy gives many options, but for a finished table, the height is never equal to just the length of the wooden support.

Working formula:

H of the finished table = H of the leg + H of the tabletop + elements that actually add height from the top and bottom.

For our project, the starting model:

• MN-111 — 390 mm;

• tabletop — 40 mm;

• preliminary total — 430 mm.

Next, you need to determine whether the mounting assembly adds anything.

Top mounting system

If the leg is attached via a plate, bushing, adapter, or another component, it's important to understand whether it is located inside the structure or actually increases the distance between the top of the leg and the top surface of the tabletop.

The mere presence of a part in the list of recommended hardware does not automatically allow you to add its thickness to the table height.

Bottom hardware

The foot pad also cannot be mechanically added to 430 mm just because the FUR-023 card specifies a size of 25×25×5 mm. You need to see how it is actually installed.

Tabletop

"40 mm" in the project should be confirmed by measuring the finished part, especially if the tabletop has already been purchased. Nominal dimensions and the actual finished size may differ slightly.

Why 430 mm is a preliminary mark, not a finished height

Let's imagine three situations.

Option A: the tabletop is actually 40 mm, the fasteners are recessed, and the foot pad barely changes the height

Then the finished table may end up close to the calculated 430 mm.

Option B: the tabletop is actually 41 mm, and the lower assembly adds a few more millimeters

The nominal 15 mm is reduced.

Option C: the armrest lowers slightly under load or when sitting down

Then even a perfectly assembled table about 430 mm high may start touching the soft upholstery, although with an empty sofa everything passed.

Because of this, you need to check not only the geometry of objects in the "nobody uses them" state, but the normal room scenario.

Armrest 445 mm: what gap to consider working

A universal rule like "need at least 10 mm" would be a fabrication here. Rooms, sofas, and tables are too different.

The working clearance is determined not by a regulatory number, but by actual use.

Upholstery softness

A rigid wooden armrest and a soft voluminous bolster behave differently. In upholstered furniture, the external lower contour can change position when a person sits down.

Floor unevenness

The table stands on four points. If the floor has a slope, one side of the top surface may be higher than the other.

Table movement

The table does not teleport under the sofa strictly horizontally. It is moved by hand, sometimes slightly turned, catches the carpet, or changes direction.

Tabletop overhang

It is the tabletop that goes under the armrest, not an imaginary horizontal line through the center of the furniture. If the edge has a profile, bevel, or protruding decorative part, that is what needs to be checked.

User scenario

Why should the table go under the sofa? To place a cup closer? To free up the walkway? To use it as a side table? The depth of insertion and required clearance depend on this.

Before purchasing MN-111, make a table 430 mm high without MN-111

This is the most practical part of the check.

For a user who is going to buy legs for the tabletop, it is not necessary to buy legs just for the height test.

Take the already purchased tabletop and place it on stable temporary supports so that the top surface is 430 mm from the floor.

Then do not look at it from afar. Use the mockup.

1. Move it up to the sofa.

2. Slide it under the armrest to the depth needed in real life.

3. Sit on the sofa.

4. Check whether the position of the armrest changes.

5. Place a cup, laptop, or another typical object on the table.

6. Pull the table out and push it back in.

7. Check whether the table catches on the carpet.

8. See whether it is comfortable to reach it with your hand.

After such a test, it becomes clear whether working at about 430 mm is sufficient at all.

Why a cardboard model of the leg shape is secondary, while a height mock-up is mandatory

To choose the appearance, you can print the silhouette of MN-111, attach a photo, or make a 3D visualization. But none of these tools answers the question about clearance under the sofa.

In this scenario, the leg shape is not the first unknown. The height is.

Therefore, first a mock-up of the top surface. Shape, wood species, and sanding come after.

FUR-023 25×25×5 mm: five millimeters in the card cannot simply be added to the table

For MN-111, the manufacturer recommends the foot pad FUR-023. Its product size is 25×25×5 mm.

After selecting the node, you can buying the FUR-023 foot.

But the phrase "FUR-023 has 5 mm, so the table will become 435 mm" is incorrect without understanding the installation.

Why:

• part of the part may work inside the contact with the leg;

• the actual support point is determined by the installed node;

• the floor surface also affects the actual mark;

• the design may include a self-tapping screw and mounting geometry.

The correct check is to measure the assembled test node or obtain an accurate mounting diagram.

Four legs — four identical foot pads

If FUR-023 is accepted into the project, the configuration must be calculated together with four legs. The issue of glides should not be resolved after the finished assembly.

The top fitting MN-111 is selected before the final measurement.

The MN-111 card recommends FUR-001-1, FUR-044, and FUR-012. Their presence near the product does not mean mandatory simultaneous use.

First, you need to understand which tabletop has already been purchased.

What is inside it

Solid wood, MDF, board, multilayer construction — this affects the possible fastening.

What area is available underneath

The size of MN-111 B×D is 82×68 mm. You need to ensure that the selected assembly physically fits and does not conflict with the edge.

What fastening does the craftsman accept

The designer or furniture maker must approve the specific scheme.

Only after this can we talk about the finished height, not the theoretical 430 mm.

To compare components, you can open the section Furniture leg hardware.

Coffee table next to the sofa: don't look for the "correct standard height" if the interior already exists

In this project, there is a more precise starting point than the average recommendation from the internet: a specific sofa is already in the room.

Therefore, its geometry is more important than general tables.

Armrest

445 mm is the upper limit for the sliding-in scenario.

Seat

Its height is important for the convenience of using the table, even if the armrest physically does not interfere.

Cushions

They affect the person's seating and the actual height of the arm.

Place of use

If the table will stand to the side and slide under the sofa, one height may be convenient. If it will be constantly in front of the sofa, the requirements change.

Perhaps the table should not go under the armrest at all

This is an important fork in the road.

Sometimes the low height is set only because the user decided in advance: "the table should slide under the sofa." But after trying it out, it turns out that almost no one uses this mode.

If the table will stand in front of the sofa or to the side, the strict 445 mm limit disappears. Then you can choose a different height that works better with the seat and the proportions of the room.

Do not worsen the table for a function that is not needed.

MN-111 fits, but a 40 mm tabletop does not: can the legs be kept

Suppose the MN-111 shape fits the interior perfectly, but the height mock-up showed: 430 mm is too close to the armrest.

It is not necessary to immediately give up the legs.

Thinner tabletop

If the project allows replacing an already purchased part, a thinner tabletop will reduce the finished height.

Another structural sublayer

Sometimes extra millimeters appear not in the tabletop itself, but in the intermediate mounting system.

Do not shorten MN-111 yourself

You cannot assume that a 390 mm wooden leg can simply be sawed off to the desired value without checking the structure, shape, and admissibility of such modification.

If a product change is required, it is coordinated with the manufacturer or a furniture specialist.

The 40 mm tabletop remains, but MN-111 does not fit: we look for a lower support

If the tabletop is already finally approved and replacing it is impractical, you need to compare lower models.

For this, it is more useful to open a narrow category to buy legs for a coffee table, rather than looking for a random leg by appearance.

Procedure:

1. determine the maximum allowable finished height;

2. subtract the actual thickness of the countertop;

3. account for the fasteners;

4. obtain the maximum allowable support height;

5. then choose the shape within this range.

Beech or oak will not change the height of MN-111

For both wood species, the model geometry remains 390×82×68 mm.

Therefore, the choice of material does not solve the problem of the 15-millimeter nominal gap.

Beech

It may be rational under a covering enamel, if this matches the project.

Oak

It makes sense if you want to preserve the visible natural texture.

First, the height

Buying an oak table "because it's beautiful" and then finding out the table doesn't fit is especially disadvantageous due to the higher cost of the set.

If you want to compare the entire range, you can Buy wooden furniture legs after determining the allowable height.

"Standard" or "Prestige" for MN-111: this is the second level of choice

The card distinguishes the quality of sanding:

• "Standard" — machine sanding;

• "Prestige" — more detailed manual preparation.

Choosing between them makes sense after MN-111 is confirmed by height.

If the table physically doesn't perform its function, more expensive sanding won't fix the geometry.

To select the material and prepare the surface, you can open Materials and quality of wooden legs.

Price of four MN-111: checking the height saves more than arguing about sanding

According to the current card, four legs cost:

These are only the legs. Hardware, finishing, and delivery are calculated separately.

The difference between four beech "Standard" and "Prestige" is 2,840 ₽.

Between oak ones — 2,360 ₽.

But if the assembled table catches the sofa, the economic damage is determined not by this difference, but by the need to change the design or buy a second set of supports.

Therefore, the cheapest "tool" in the project is a temporary height mock-up.

Do I need to buy one MN-111 for testing?

For height testing — no.

The card allows shipment from one piece, but it makes sense to buy one leg if you need to evaluate:

• real shape;

• sanding quality;

• the wood;

• color;

• the mounting assembly.

To answer whether a 430 mm table will fit under a 445 mm armrest, a correct height mock-up is sufficient.

Mistakes that make a table "pass on paper" but not in the room

Mistake 1. Treating 390 + 40 as the final height

Reason: no mounting hardware selected.

Consequence: the finished dimension differs.

Prevention: final calculation only after the mounting assembly.

Error 2. Automatically add 5 mm FUR-023

Reason: the size of the thrust bearing is taken as an increase in height.

Consequence: the calculation may be incorrect.

Prevention: measure the installed unit.

Error 3. Measure the sofa without a person

Reason: the armrest is soft.

Consequence: when sitting, the gap decreases.

Prevention: check the scenario in use.

Error 4. Buy oak before the mockup

Reason: the material was chosen before the geometry.

Consequence: the expensive set doesn't fit.

Prevention: first, a 430-millimeter mockup.

Mistake 5. Looking for the "standard height of a coffee table"

Reason: they try to replace the actual interior with an averaged norm.

Consequence: the table may be convenient "according to the table," but inconvenient for a specific sofa.

Prevention: work from the existing sofa.

When MN-111 doesn't need to be purchased yet

It's better not to order four legs if:

• the actual thickness of the tabletop hasn't been measured;

• 445 mm of the armrest is an approximate figure;

• The table must fit under the sofa, but there is no height mockup;

• The top mounting is not selected;

• FUR-023 is not accepted or not consciously excluded;

• The finished floor will still change;

• The behavior of the soft armrest has not been checked;

• The solution is based only on the formula 430 < 445.

When four MN-111 can already be ordered

The purchase becomes justified when:

1. The armrest is measured in its actual position;

2. The tabletop has its final thickness;

3. The top at 430 mm is verified with a mockup;

4. the table slides to the required depth;

5. top mounting selected;

6. FUR-023 accounted for in the actual assembly;

7. finish height confirmed;

8. beech or oak selected;

9. Standard or Prestige selected;

10. current price re-verified;

11. four identical legs confirmed.

After that, you can order wooden legs MN-111 with one specification.

Example:

MN-111 / 390×82×68 mm / beech or oak / Standard or Prestige / 4 pcs. / tabletop actual ___ mm / target finish height ___ mm / armrest limit 445 mm / top mounting ___ / FUR-023 ___ pcs. / finish ___.

Where to compare alternatives if 390 mm doesn't fit

If the MN-111 layout doesn't work, don't try to force the project through.

• buy furniture legs — general catalog;

• to buy legs for a coffee table — narrow filter by purpose;

• Buy unpainted wooden legs — options for custom finishing;

• Furniture leg hardware — components;

• delivery conditions for furniture legs — before placing an order.

Bottom line: 15 mm on the calculator is not 15 mm in the room

The project has very attractive arithmetic:

390 + 40 = 430 mm.

445 − 430 = 15 mm.

But the coffee table does not exist in the formula. It has fasteners, support pads, four points of contact, a real tabletop, movement across the floor, and a specific sofa with soft upholstery.

Therefore, the decision on MN-111 is made as follows:

not buying legs → assembling the table → checking,
а
modeling the height → checking the sofa → approving the fasteners → calculating the final dimension → buying four identical legs.

If the 430-millimeter mockup fits freely under the sofa and, after accounting for the real hardware, a comfortable working clearance remains, MN-111 meets the main criterion of this project.

If the mockup already fits tightly, do not expect expensive oak, "Prestige," or careful assembly to fix the problem. Then either the leg height, the tabletop, or the table usage scenario itself is changed.

FAQ

What is the height of MN-111?

390 mm.

What is the full size of MN-111?

390×82×68 mm according to parameters A×B×D.

Is MN-111 suitable for a coffee table?

The card and categories allow considering the model for such furniture, but specific compatibility is determined by the design and final height.

What will be the nominal height of the table with MN-111 and a 40 mm tabletop?

390 + 40 = 430 mm before accounting for elements that actually add height.

Will it be exactly 430 mm?

Not necessarily. The actual tabletop, top mounting hardware, and bottom assembly need to be considered.

Will a 430 mm table fit under a 445 mm armrest?

Nominally, 15 mm remains. Actual compatibility is checked with a mockup in the room.

Do I need to consider the foot pad?

Yes, if it is used. But its listed 5 mm cannot be automatically added to the total height without understanding the installation.

What size is FUR-023?

25×25×5 mm.

How many FUR-023 are needed for four legs?

If the design includes one leveling foot per leg — four. The specific layout needs to be confirmed.

How to check the table against the sofa?

Place the countertop on temporary supports so that its top is at the calculated height, and check the real sliding-in scenario.

Can a mockup be made before purchasing the legs?

Yes. For height, this is the most rational test.

Is it necessary to buy one MN-111 for testing?

For height — no. One real leg is useful for shape, material, sanding, and the mounting assembly.

What to choose — beech or oak?

After checking the height. Beech and oak do not change the 390 mm dimension.

How does 'Standard' differ from 'Prestige'?

The card separates machine and more detailed manual sanding.

What fasteners are recommended for MN-111?

The card lists FUR-001-1, FUR-044, FUR-012, and FUR-023. This does not mean that all items must be used together.

How many MN-111 should be ordered?

For a classic four-legged coffee table in the project under consideration, there are four, if the design is approved exactly as such.

Where to buy legs for a coffee table?

Can the MN-111 be shortened if the table doesn't fit?

Such modification should not be considered automatically acceptable. It needs to be coordinated with the manufacturer or a furniture design specialist.

What to do if 430 mm is already too high?

Check a lower model of legs, a thinner tabletop, or abandon the scenario of sliding it under the sofa.

Can a soft armrest reduce the gap?

Yes, its position may change under load, so it's useful to check in a real scenario.

Why can't you rely only on the "standard coffee table height"?

Because the project already has a specific constraint — an existing sofa with a 445 mm armrest.

When is it too early to buy MN-111?

When there is no height mockup, fasteners are not selected, or the actual finished height is unknown.

When can MN-111 be ordered?
