Best guest beds
A sofa bed compromises the mattress so it can be furniture. A folding mattress in a cupboard does not.
I earn a commission if you buy through some links on this page. It never changes what I recommend, and I publish negative verdicts on brands I earn from. Editorial independence.
The guest bed question is really a question about what the room has to do the rest of the time.
If the room needs seating, a sofa bed. If it needs nothing, a folding mattress stored in a cupboard sleeps better and costs less, because it does not have to fold into furniture.
The constraint that decides both is depth. A sofa bed mattress is typically 10 to 15 centimetres against 28 to 35 for a real one, because that is what fits inside a sofa.
And the whole category shares one problem: you are buying for someone whose weight and sleeping position you do not know. That makes medium-firm genuinely correct rather than a fudge, and it makes two pillows per person the best value decision you can make.
The picks
The pick, if you want one answer
Silentnight Sleep Now Range, 6.7 / 10. A proper single mattress on a frame, which is what a guest room should have if it can hold one.
| Product | Best for | From | Score |
|---|---|---|---|
| Silentnight Sleep Now Range | Best if the room takes a real bed | From £169 | 6.7 / 10 |
| Inofia Tri-Fold Mattress | Best folding mattress | Budget | 6.5 / 10 |
| Emma Sofa Bed | Best if you need the sofa | Mid range | 6.6 / 10 |

Silentnight Sleep Now Range: Best if the room takes a real bed
From £169 · 6.7 / 10
From £169, from a manufacturer trading since 1946. Nothing folding or convertible matches a real mattress, and at this price a permanent guest bed costs less than most sofa beds. Confirm the springs are pocketed if two guests may share.
Buy it if
The room can hold a permanent single or double.
Do not buy it if
The room has to be something else most of the time.

Inofia Tri-Fold Mattress: Best folding mattress
Budget · 6.5 / 10
A folding mattress does not compromise for furniture, so it sleeps better than a sofa bed at a fraction of the price. Expect it to be firm and to show fold lines, which is inherent to the construction rather than a fault.
Buy it if
You want good occasional sleeping and storage in a cupboard.
Do not buy it if
The room needs seating.

Emma Sofa Bed: Best if you need the sofa
Mid range · 6.6 / 10
Scores 6.6, and the score reflects the category rather than the product. If you do buy one, lie on it in the shop for a few minutes: a metal support bar you can feel in thirty seconds is one your guest feels all night.
Buy it if
The room genuinely needs seating the rest of the time.
Do not buy it if
Guests stay often or for long periods.

Origin Hybrid Mattress: Best permanent guest mattress
£265 · 8.0 / 10
Scores 8.0. Up to 3,000 pocket springs at £265, and worth knowing for a rarely used room: foam degrades with time as well as use, so springs are worth paying for more in a guest room than in a main bed.
Buy it if
You want a guest room that people actually want to stay in.
Do not buy it if
The room is used a couple of nights a year on a tight budget.

The options, compared honestly
| Option | Sleeping | Room use |
|---|---|---|
| Permanent single or double | Best. A real mattress. | Takes the room permanently. |
| Folding mattress in a cupboard | Good. Firm, with fold lines. | None when stored. |
| Day bed or trundle | Good. Real mattresses, depth limited on the trundle. | Seating, permanently in place. |
| Sofa bed | Fair. Thin mattress, possible bar. | Full seating. |
| Air bed | Poor for more than a night or two. Loses pressure, cold from below. | None when stored. |
The row people underrate is the second. A folding mattress is the cheapest way to sleep a guest properly, and the only cost is cupboard space.
Buying for people you cannot measure
Everywhere else on this site, the right mattress depends on your weight and sleeping position. A guest bed removes both variables.
So medium-firm is genuinely correct here: firm enough that a heavier guest does not bottom out, soft enough that a lighter side sleeper is not lying on a board. It is the firmness that fails least badly across the widest range of bodies.
The same logic makes two medium pillows per person the best value decision on this page. Pillow height depends on shoulder width and sleeping position, and you cannot know a guest's: a side sleeper stacks them, a back sleeper uses one, a front sleeper pushes both aside. That is the hotel solution and it works.
What a rarely used bed needs that a main bed does not
Springs rather than foam. Foam degrades with time as well as use, so a foam mattress in a spare room can be noticeably softer after six years having been slept on sixty times. Steel does not age that way.
Airing. Spare rooms are unheated, unventilated and closed for weeks, which is the condition in which moisture collects. Turn back the bedding for a day before guests arrive and open a window occasionally between visits.
Rotation. Rotate head to foot a couple of times a year even though it is barely used. It takes a minute and prevents settlement in one spot.
A protector. Guests will not tell you about a spill, and a stain voids most mattress guarantees absolutely.
The cheap things that make a guest room feel considered
Bedding that fits. Deep fitted sheets sized to the actual mattress depth, because standard UK sheets are cut for about 25 centimetres and modern mattresses run deeper.
A 7 to 10.5 tog duvet, which suits most modern UK bedrooms. Thirteen and a half is a convention from draughtier housing and will cook a guest in a small warm room.
A spare blanket at the foot of the bed, which lets a cold guest add warmth without asking, and covers the range a single duvet cannot.
Somewhere to put a phone and a glass of water. Trivial, and it is the thing guests notice.
What not to buy
A sofa bed as someone's regular bed. The mattress depth makes that unreasonable.
A soft or a firm mattress for guests. You cannot measure them, so the extremes are the wrong bet.
Foam for a rarely used room. It ages on the calendar rather than on use.
An air bed for more than a night or two. It loses pressure and it is cold from underneath.
Single fixed-height pillows. Two medium ones each covers far more guests.
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, and the same category limits apply: judge it as occasional sleeping and plan for a topper. |
| Emma Original Lite | A three-zone pocket spring layer at £199 with a 200 night trial, which is a strong permanent guest mattress if the room can take a bed. |
| Silentnight Airmax Topper | Scores 7.4. A topper does more for a sofa bed than an expensive sofa bed does, and it stores flat between visits. |
| Inofia Elegant | Twenty-seven centimetres and a spring core at around £210, which is a sound permanent guest mattress for occasional use. |
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.
See editorial independence, corrections and the author page.
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
What is the best guest bed if I have the space?
A permanent single or double with a real mattress, which nothing folding or convertible matches. Silentnight's Sleep Now range starts at 169 pounds, which is less than most sofa beds.
Is a folding mattress better than a sofa bed?
For sleeping, usually yes, because it does not have to fold into furniture, so it is not limited to the 10 to 15 centimetres a sofa cavity allows. The cost is that it gives you no seating.
What firmness should a guest mattress be?
Medium-firm, and here it is genuinely correct rather than a compromise, because you are buying for people whose weight and sleeping position you cannot know. It is the firmness that fails least badly across the widest range of bodies.
What pillows should I put in a guest room?
Two medium pillows per person. A side sleeper stacks them, a back sleeper uses one and a front sleeper pushes both aside, which covers the full range for the price of a few pillows.
