A coffee table is not defined by what the listing calls it. It is defined by one number — the height of its top against the height of your sofa seat — and on that test a third of the tables filed as coffee tables in this catalogue are not coffee tables at all. We pulled every product in our Coffee Tables and Side Tables collections, measured each individual table top in each set, and compared all 209 of them against the published seat height of every sofa in our Sofas & Seating range. The pattern that came out is the reason so many living rooms end up with a table nobody quite uses.
Short answer. A coffee table should sit level with the top of your sofa seat cushion or up to 5 cm below it. Measure the seat, not the room. Sofa seats in our range run 37–50 cm with a median of 45 cm, so most people want a table 40–45 cm high. A side table belongs higher: between the seat line and about 24 cm above it, which is where your elbow rests when you sit down.
Why does coffee table height depend on the sofa and not the room?
Because the table is a surface you use while seated, and the thing that sets the height of a seated hand is the seat. Put the top above the seat line and you have to lift your forearm up and over your own thigh to set a mug down; the movement is small but you make it forty times an evening. Put it far below and you lean out of the back of the sofa every time. Between those two failures there is a narrow band, and it moves with the sofa.
Three UK sizing guides agree on roughly where that band is. Furniture in Fashion puts a coffee table at 40–50 cm and "within 5 cm either way" of the seat cushion. FCI London narrows it to 40–46 cm and says the table should sit 2.5–5 cm below the seat. Homary UK gives 41–46 cm and the same 2.5–5 cm, "generally on the lower side".
The disagreement is worth resolving rather than averaging. Two of the three sources say lower, not level; one allows 5 cm either way. The looser version is really the dining exception leaking in — both Furniture in Fashion and FCI London separately note that a table you eat from wants to be higher than the seat, at 50–53 cm. That is a different piece of furniture doing a different job. For a table you put drinks on, treat the seat line as a ceiling, not a midpoint.
What is the Step Test?
Three numbers, and you can run it on any listing anywhere:
- The seat line. Floor to the top of your sofa seat cushion, with the cushion compressed by someone sitting on it. This is the reference for everything else.
- The step. The table top height minus the seat line. For a coffee table you want the step between 0 and −5 cm. Positive means the table is above the seat, and it is a side table now whatever the listing says.
- The elbow line. The seat line plus 24 cm. That is the median British adult's seated elbow rest height, from RoyMech's anthropometric tables (men 21/25/29 cm at the 5th, 50th and 95th percentile; women 19/23.5/28 cm). It is the ceiling for a side table.
So the seat line is the border. Below it, down 5 cm, is coffee-table country. Above it, up to the elbow line, is side-table country. A table's height decides which side of the border it is on, and the listing's category name has no vote.
| Coffee table | Side table | |
|---|---|---|
| Reference | The seat line: floor to the top of the compressed cushion | The armrest, or the elbow line if you cannot measure the arm |
| Target step | 0 to −5 cm | 0 to +24 cm |
| On a 45 cm seat | 40–45 cm | 45–69 cm |
| Too high feels like | Lifting your forearm over your thigh | Shrugging your shoulder to put a glass down |
| Too low feels like | Leaning out of the back of the sofa | Reaching down past the arm, so use it as a coffee table instead |
| In this catalogue | 61 of 141 tops in Coffee Tables qualify | 29 of 53 Side Tables products have a top in the designers’ 50–61 cm band |
How many coffee tables are actually at coffee-table height?
We measured all 141 individual table tops across the 90 products in the Coffee Tables collection — individual, because nearly half of those products are sets containing two or three tables at different heights. Then we ran the three thresholds against the median 45 cm sofa seat.
Lead with the kindest number and the collection looks healthy. Apply the rule the guides actually give — level or lower — and it thins out fast: 61 of 141 tops qualify, and 27 of them sit at 50 cm or more, which is 5 cm or more clear of the seat line. Twenty products in the Coffee Tables collection have a tallest top at 50 cm or above. Eight have every top at 50 cm or above. Those eight are side tables that happen to be filed with the coffee tables, and the height is on the listing if you look for it.
The split between single tables and sets matters more than anything else here. Of the 43 single tables in the collection, 31 pass the level-or-lower test. Of the 47 sets, only 24 do — and that undersells the problem, because passing means one of the two or three tables in the box works.

Why does a set of two nesting tables rarely give you two coffee tables?
This is the finding we did not expect, and it is the one worth knowing before you spend. There are 50 multi-table nesting sets across the two collections, 47 of them in Coffee Tables. A set nests because the tables are different sizes, and different sizes here means different heights: the median height gap between the tall table and the short one is 6 cm, and 15 of the 50 sets have a 10 cm gap.
Six centimetres is the entire width of the coffee-table band. So the arithmetic is unforgiving. Against the level-or-lower rule, only 6 of the 50 sets have two tops inside the band; 19 have exactly one; and 25 have none at all. Loosen it to 5 cm either way and it is still only 16 sets out of 50 with two usable tops.
Read plainly: buying "a set of two coffee tables" usually buys you one coffee table and one low plant stand, or two side tables. That is not necessarily a bad purchase — a 36.5 cm table beside an armchair is a fine place for a book, and the nesting does save floor space — but it is not two coffee tables, and the listing will not tell you so. Look for the two heights in the Dimensions block and subtract.

Where does a side table belong?
Higher than most people put one, and lower than a third of the range allows. The design convention is neat: Ideal Home quotes Ethan Fox of Furniture World saying a side table should sit "within 5 cm of the height of your sofa's armrest", Tanya Rechberger of King Living calling it "an extension of your sofa", and Lucy Mather of Arighi Bianchi putting the practical answer at 50–61 cm.
The elbow line explains why that band and not another. Sit on a 45 cm sofa seat and your elbow rests about 23.5 cm above the cushion if you are a median British woman, 25 cm if you are a median British man — so roughly 69 cm from the floor. Anything at or below that you can reach with the shoulder still down. Above it and you shrug to put a glass down. Drop to a 41 cm sofa and a 5th-percentile reach and the ceiling falls to 60 cm.
Ten of the 53 products have every top above the 69 cm elbow line. That is not a fault in them — they are the bedside tables, the record-player stands at 74 cm, the overbed tables that reach 100 cm, and the tall floral-cut-out pair at 75 cm. They are filed under side tables because that is the shape of the furniture, and they are excellent beside a bed, where the reference height is a mattress and not a sofa seat. Beside a sofa they are too high, and the height is the way to tell.

Why can you not apply the designers’ rule to any sofa listing?
Because the number it depends on is missing. We checked all 147 products in our seating range: not one publishes an armrest height. Two give an armrest length and width. Meanwhile 46 of the 147 publish no seat height either, mostly the convertibles, where the listings give a sofa footprint and a bed size and skip the seat. So of the two measurements a table buyer needs, one is absent everywhere and the other is absent from a third of the range.
We would rather say that plainly than pretend otherwise, and we have flagged it internally. In the meantime the fix takes a tape measure and two minutes: sit on the sofa, have someone measure floor to the top of the compressed cushion, then measure floor to the top of the arm. The first number is your seat line. The second is the one to keep a side table within 5 cm of. Write both on your phone before you open a product page.
How long should a coffee table be, and how far from the sofa?
All three sizing guides give the same proportion: about two thirds of the sofa's length. A 144 cm two-seater wants roughly 96 cm of table; a 199 cm three-seater wants about 133 cm. That is where our range runs out. The longest fixed-top coffee table we stock is 115 cm and it is currently out of stock; the longest available with a fixed top is 106 cm. Exactly one product in the range reaches 133 cm, and only by extending — the extendable table that runs 108 to 178.5 cm. If you have a full three-seater, that is the honest answer, and it is worth knowing before you order something that will look undersized in front of it.
For the gap, Homary UK puts 41–46 cm between the table edge and the sofa, close enough to reach a mug without standing. Living Etc quotes spatial designer Delphine Bouvet on about 45 cm clear around a coffee table and 90 cm for a main walkway, while noting that in small British homes "compromises are often necessary". In a room too tight for both, keep the reach distance and give up the walkway — a nesting set or a C-shaped table that tucks away is the standard answer, and our small living room guide works through the layout side of it.
Does paying more get you a better-fitting table?
No, and the correlation runs the other way. Across the range, price against the tallest top in the product correlates at minus 0.46; among the 43 single coffee tables alone it is minus 0.30. Dearer tables are lower tables. The reason is straightforward once you see the catalogue: money buys width, storage and a solid top, all of which come in a low slab, while the cheap end of the range is small tall metal-framed accent tables. This is the same pattern our bookcase guide found, where price correlated at minus 0.29 with how well a shelf held books, and the opposite of what our armchair guide found, where paying more bought a deeper seat than most people can use.
What about lift-top, extendable and height-adjustable tables?
They are the one honest way out of the single-height problem, and their numbers are worth reading carefully. A lift-top sits at coffee height closed and rises for eating or laptop work: the 95 cm industrial model goes 46.5 to 59 cm, the 105 cm oak-effect one 49 to 61.5 cm. Both land in the dining band FCI London gives at 50–53 cm and above, which is right for a plate on your knees rather than a desk.
Two cautions from the descriptions. First, the raised top is rated far lower than the closed one: the 95 cm model states 2 kg on the lifted top against 15 kg overall, and the 105 cm model 5 kg lifted against 100 kg overall. That is a laptop and a plate, not a printer. Second, a closed height of 49 cm is already above a 45 cm seat line, so a lift-top often trades a perfect coffee-table height for the ability to rise. The only product in either collection that covers both bands properly is the height-adjustable C-shaped table, 44.5 to 79 cm in one piece of furniture.

How do you buy a table in five steps?
- Measure the seat line. Floor to the top of the compressed seat cushion. Write it down.
- Measure the arm. Floor to the top of the armrest. That is your side-table target, plus or minus 5 cm, and no listing will give it to you.
- Set your two bands. Coffee table: seat line down 5 cm. Side table: seat line up to the elbow line, seat line plus 24 cm.
- Read the height for every table in the box. On a set that means two or three numbers. Subtract the smallest from the largest — if the gap is 10 cm, only one of them can land in a 5 cm band.
- Then check length and clearance. Two thirds of the sofa, 41–46 cm of gap, 45 cm clear around.
Worked example. A 144 cm corduroy two-seater from our range publishes a 45 cm seat. Seat line 45, so the coffee-table band is 40–45 cm and the side-table band is 45–69 cm. Two thirds of 144 cm is 96 cm, so a 94–100 cm table is right and a 78 cm round one will read small. The 100 cm tambour table at 40 cm high is a step of −5: bottom of the band, correct. Beside it, a 58 cm narrow side table sits 13 cm above the seat and 11 cm below the elbow line. Neither decision needed a showroom.
What do people get wrong?
- Buying by the collection name. Eight products in the Coffee Tables collection have every top at 50 cm or above. The height is published; the category is not a spec.
- Assuming a set of two means two coffee tables. It means that in 6 of 50 cases.
- Measuring the sofa's overall height. The 73–91 cm figure on a sofa listing is the top of the back. It is no use to you here.
- Measuring an uncompressed cushion. A 20 cm foam-and-spring seat loses real centimetres under weight. Sit on it.
- Going taller for a dining-height table without deciding to. 50–53 cm works for eating and is wrong for drinks. Pick one on purpose.
- Ignoring the lifted-top load rating. 2 kg on a raised surface rules out more than people expect.
Frequently asked questions
How high should a coffee table be?
Between the top of your sofa seat cushion and 5 cm below it. For the median sofa in our range, which has a 45 cm seat, that means a table 40 to 45 cm high. Measure your own seat height rather than assuming: sofa seats here run from 37 to 50 cm.
Should a coffee table be higher or lower than the sofa seat?
Lower, or level. Two of the three UK sizing guides we checked say specifically lower, by 2.5 to 5 cm. A table above the seat line means you reach up and over your own thigh to put a cup down, which is why the height on a listing decides whether a table works.
What height should a side table be next to a sofa?
Between the seat line and the elbow line: your sofa's seat height, up to about 24 cm above it. For a 45 cm sofa seat that is roughly 45 to 69 cm. Designers usually shorten this to within 5 cm of the armrest, which lands most people between 50 and 61 cm.
Can a nesting set give me two coffee tables?
Usually not. Across the 50 nesting sets in our two table collections the median height gap between the tall table and the short one is 6 cm, and 15 sets have a 10 cm gap. Only 6 of the 50 have two tops inside the coffee-table band; 25 have none at all.
How long should a coffee table be compared with the sofa?
About two thirds of the sofa's length. A 144 cm two-seater wants roughly 96 cm, a 199 cm three-seater roughly 133 cm. Worth knowing before you shop: only one table in our range reaches 133 cm, and only when extended.
How much space should I leave between the sofa and the coffee table?
Around 41 to 46 cm, close enough to reach a mug without standing up. Leave about 45 cm clear all the way round the table, and keep a main walkway through the room at about 90 cm where the room allows it.
Why do sofa listings not tell me the armrest height?
They mostly do not, ours included. Not one of the 147 sofas in our seating range publishes an armrest height, and 46 of them publish no seat height either. Both numbers are the ones a table buyer needs, so measure your own sofa with a tape before ordering.
Do lift-top coffee tables solve the height problem?
Partly. A lift-top sits at coffee-table height when closed and rises to roughly 59 to 62 cm for eating or working, which is dining-adjacent rather than a desk. Check the closed height first, because that is the one you live with, and check the load rating on the raised top.
