Best chair beds
A chair bed folds a single mattress into three, which puts two hinges directly under the sleeper.

A chair bed is an armchair that unfolds into a single bed. It is the most space-efficient convertible there is, and it pays for that with the most compromised mattress in the category.
The reason is arithmetic. A sofa bed folds a mattress once. A chair bed folds a single mattress into three sections to fit inside an armchair footprint, which puts two hinge lines under the sleeper, usually across the shoulders and the hips.
The mattress is also thin by necessity, typically 8 to 12 centimetres, because that is what fits. For one or two nights that is manageable. For a week it is not.
So the real question is whether the room needs an armchair, because that is the only thing a chair bed does that its alternatives do not.
The picks
The pick, if you want one answer
Inofia Tri-Fold Mattress, 6.5 / 10. A folding mattress, which has no hinges under the sleeper and costs a fraction as much.
| Product | Best for | From | Score |

Inofia Tri-Fold Mattress: Best alternative
Budget · 6.5 / 10
A tri-fold mattress folds in the same three sections and unfolds flat with no frame hinges underneath, which is the whole difference. It costs far less and sleeps considerably better.
Buy it if
You have floor space for guests and cupboard space between visits.
Do not buy it if
The room genuinely needs a chair.

Silentnight Airmax Topper: Best fix for a chair bed you own
Budget to mid · 7.4 / 10
Scores 7.4. A topper over a chair bed does more than any upgrade to the chair itself: it spreads load across the hinge lines and stops the guest feeling the frame through thin foam. Spacer mesh adds the least bulk.
Buy it if
You have a chair bed and a guest arriving.
Do not buy it if
You are buying from scratch.

Emma Sofa Bed: Best if you need more seating
Mid range · 6.6 / 10
Scores 6.6. A sofa bed folds the mattress once rather than twice, which is a meaningfully better sleeping surface, and takes considerably more room. Lie on it in the shop, because a bar you feel in thirty seconds is one your guest feels all night.
Buy it if
Two or three people need to sit, not one.
Do not buy it if
Floor space is the binding constraint.

Silentnight Sleep Now Range: Best if you can keep a real mattress
From £169 · 6.7 / 10
From £169, from a manufacturer trading since 1946. A real single mattress costs less than most chair beds and is a completely different night's sleep.
Buy it if
There is anywhere at all to store a single mattress.
Do not buy it if
Storage is the binding constraint.

Where the folds fall, and why it matters
Two hinges under one sleeper
A three-fold mattress has fold lines roughly a third and two thirds of the way down, which typically puts one across the shoulders and one across the hips, where most of the weight is.
Lie on it in the shop for a few minutes rather than sitting on it. If you can feel a hinge in two minutes, a guest feels it for eight hours.
Two things reduce it. A thicker mattress, which few chair beds have room for, and a topper, which spreads load across the lines and is the practical answer.
Check whether the sections are separate cushions or a continuous mattress with fold points. Separate cushions can separate under a sleeper, which is worse than a hinge.
What to check before buying
| Check | Why |
|---|---|
| Mattress depth | Under about 10cm, a heavier guest feels the frame |
| Unfolded length | Frequently shorter than a standard single at 190cm |
| Floor space when unfolded | Measure it. It occupies far more than the chair footprint. |
| Weight limit | Stated, and usually lower than a bed's |
| Mechanism effort | If it is hard to unfold, it stops getting used |
| Removable washable cover | It is furniture the rest of the year |
The second row catches people. Many chair beds unfold shorter than a standard single, which is fine for a child and not for a tall adult, and standard single bedding will not fit properly either.
Bedding for a chair bed
Measure before buying sheets. A non-standard length means a standard single fitted sheet will be loose or short, and a loose sheet on a folding surface bunches into the hinge lines.
Two medium pillows. You are buying for someone whose shoulder width and sleeping position you do not know: a side sleeper stacks them, a back sleeper uses one, a front sleeper pushes both aside.
A protector, because thin foam absorbs everything and guests will not tell you.
A 7 to 10.5 tog duvet, which suits most modern UK bedrooms, and a spare blanket so a cold guest can add warmth without asking.
When a chair bed is the right answer
A study or box room that needs one seat and occasionally has to sleep someone. This is the situation the product was designed for and it does it well.
A child's room where a friend stays occasionally, and the length limitation does not matter.
A flat with no storage at all, where a folding mattress has nowhere to live.
When it is not: regular guests, anyone staying more than two nights, tall adults, and anyone who struggles to get up, since chair beds sit low and the frames flex.
What not to do
Judge it by sitting in it. Unfold it and lie down for a few minutes.
Assume it is single bed length. Many unfold shorter than 190 centimetres.
Use it for a guest staying a week. Two hinges and thin foam wear quickly.
Buy one without measuring the unfolded floor space.
Skip the topper. It does more than any upgrade to the chair.
Also considered, and why they are not here
A roundup is only as useful as what it leaves out, so here is what was assessed and rejected for this list.
| Product | Why it is not on the list |
|---|---|
| IKEA Sofa Bed | Scores 6.5. Sensible value, folds once rather than twice, and takes considerably more room than a chair bed. |
| Simba Topper | The highest scoring topper here at 7.5. Over a chair bed it spreads load across the hinge lines, which is the single most effective improvement. |
| Emma Original Lite | A three-zone pocket spring layer at £199, which is what the money buys if there is room for a real bed. |
| Inofia Elegant | Twenty-seven centimetres and a spring core at around £210, and nothing that folds into an armchair. |
How this list is made, and who made it
Independence
No brand pays to appear on this site and no placement is sold. Some links earn a commission if you buy, which never changes a score, an order or a verdict. Several of the lowest scores here are on products that carry commission, and several recommendations carry none.
Who writes this. Kyle Klinkradt has worked in the mattress and bedding industry for over ten years across retail, distribution and brand partnerships, and has handled, sold or assessed products from every major UK bed-in-a-box brand. Every review on this site is written by one person, so the scores mean the same thing from page to page.
What the assessment is. Construction specifications against what they physically do: spring height and where in the mattress it sits, spring count for the size, gauge, whether the base is sprung or foam, foam density where it is published, comfort layer depth and material. Then the commercial terms that decide what you are actually buying: trial against returns policy, guarantee length against the company's UK trading history at Companies House, and the regulatory record.
What it is not. This is not a laboratory. I do not publish pressure-mapping data or claim to have slept eight years on every mattress here, because nobody has and pages that imply otherwise are not telling you the truth. Where a judgement rests on construction rather than long-term use, the review says so.
What gets a product removed. Leaving the UK market, a specification change that makes the review inaccurate, or a corrected fact. Brands that have withdrawn are kept on the site with the score removed rather than quietly deleted, because people still search for them.

How these were chosen
Every product here has its own review on this site with a score out of 10, and the score is a judgement rather than an average. Nothing appears in a list because it pays more.
A score is against the market, not against its own range. The cheapest mattress in a lineup is usually priced to make the model above it look reasonable, and the flagship of a budget range has risen into a bracket where better brands compete. Both are judged against what else you could buy for the money.
Everything listed can actually be bought in the UK. That is not a given: Casper withdrew in July 2020 and Leesa no longer sells here, and both still appear in current British roundups with affiliate links attached.
I do not pad the list. Where only three or four products genuinely qualify, there are three or four. A list of seven when the category contains four good ones is a list with three bad recommendations in it.
Prices move constantly. Judge the cash price on the day rather than any percentage beside it. See every review on this site or where the real savings are.
Questions people ask
Are chair beds comfortable to sleep on?
For one or two nights, manageable. A chair bed folds a single mattress into three sections, which puts two hinge lines under the sleeper, typically across the shoulders and the hips, and the mattress is thin by necessity at 8 to 12 centimetres.
Is a chair bed the same length as a single bed?
Frequently not. Many unfold shorter than the standard single 190 centimetres, which is fine for a child and not for a tall adult, and standard single bedding will not fit properly.
What is better than a chair bed?
A folding mattress, which folds in the same three sections but unfolds flat with no frame hinges underneath, costs far less and sleeps considerably better. The chair bed's only advantage is that it is also a chair.
How do I make a chair bed more comfortable?
A topper, which spreads load across the hinge lines and stops a guest feeling the frame through thin foam. Spacer mesh adds the least bulk for the effect.
