Best air beds and air mattresses
An air bed goes soft overnight even when it has no leak, and it takes heat out of you from below.

Air beds are cheap, pack away to nothing, and have two problems that are physics rather than quality.
They get cold. A large volume of air separated from you by a thin sheet of PVC is not insulation. Air inside the bed circulates, carries heat away from your body and loses it to the floor. People routinely report being cold on an air bed in a warm room, and adding blankets on top does not fix it, because the heat is leaving downward.
They go soft. Air contracts as it cools. A bed inflated in a warm room at 10pm is at a lower pressure by 3am when the room has dropped a few degrees, with no leak involved at all.
Both are manageable, and neither goes away.
The picks
The pick, if you want one answer
Inofia Tri-Fold Mattress, 6.5 / 10. A folding mattress, which packs away like an air bed and sleeps like a mattress.
| Product | Best for | From | Score |
|---|---|---|---|
| Inofia Tri-Fold Mattress | Best alternative overall | Budget | 6.5 / 10 |
| Silentnight Sleep Now Range | Best if guests come regularly | From £169 | 6.7 / 10 |

Inofia Tri-Fold Mattress: Best alternative overall
Budget · 6.5 / 10
A folding mattress is the honest answer to most air bed use: it stores in a cupboard, needs no pump, does not deflate, and does not conduct your body heat into the floor. Expect it to be firm and to show fold lines.
Buy it if
You want something that stores away and actually sleeps well.
Do not buy it if
You need something that packs into a bag the size of a pillow.

Silentnight Sleep Now Range: Best if guests come regularly
From £169 · 6.7 / 10
From £169, from a manufacturer trading since 1946. If guests stay more than a few nights a year, a real mattress costs about the same as a good air bed and is a different experience.
Buy it if
You have anywhere at all to keep a real single mattress.
Do not buy it if
Space is the binding constraint.

Silentnight Airmax Topper: Best fix if you already own an air bed
Budget to mid · 7.4 / 10
Scores 7.4. A topper over an air bed solves the two worst parts: it puts an insulating layer between the sleeper and the cold air, and it spreads load so the surface feels less like a balloon. This is the single most effective thing you can do with an air bed you already own.
Buy it if
You have an air bed and guests arriving.
Do not buy it if
You are buying from scratch.

Why you get cold, and what fixes it
Insulate underneath, not on top
The heat is leaving downward, so more blankets on top do almost nothing. What works is a layer between you and the air chamber.
In order of effect: a mattress topper on the air bed, which is the most effective; a folded duvet or blanket underneath the sheet, which is free; and a rug or foam underlay beneath the whole bed, which reduces loss into a cold floor.
This is the same problem campers solve with an insulated mat, and the same reason a mattress on a cold floor develops condensation underneath: a cold surface below a warm body is where heat and moisture both go.
Why it goes soft, and how to manage it
Air contracts when it cools. A bed inflated firm in a warm room will be softer once the room cools overnight, and that is not a fault.
Two practical responses. Inflate it a couple of hours before bedtime so the air inside reaches room temperature, then top it up just before use. And do not over-inflate, which stresses the seams and makes the surface harder rather than more supportive.
Genuine leaks are usually at the valve or along a welded seam. To find one, inflate it, brush soapy water over the surface and watch for bubbles, and check the valve first because it is the commonest site.
If you are buying one anyway
| Feature | Why it matters |
|---|---|
| Internal coil or beam construction | Holds a flatter surface than a simple chamber, which sags in the middle |
| Built-in pump | Convenience, and it is the component most likely to fail |
| Flocked top surface | Stops sheets sliding off, which is the other everyday annoyance |
| Raised or double height | Easier to get up from, and more air to lose heat into |
| Material thickness | Puncture resistance. Thin PVC is where cheap beds fail. |
Note the trade in the fourth row: a raised air bed is considerably easier to get out of, and a larger air volume also means more circulation and more heat loss.
When an air bed is genuinely the right answer
One or two nights. Unexpected guests, a house move, a night on a friend's floor. The problems matter less over one night than over a week.
No storage space at all. A deflated air bed is the only bed that packs into a cupboard shelf.
Camping and travel, where the alternative is the ground.
When it is not: as anyone's regular bed. The surface offers no consistent support, it cools you from below, and it needs topping up. If someone is sleeping on one for more than a couple of weeks, that is a problem to solve rather than a setup to optimise.
What not to do
Pile blankets on top to fix the cold. The heat is leaving downward.
Over-inflate it. It stresses the seams and makes the surface harder, not more supportive.
Inflate it in a warm room and expect it to stay firm. Air contracts as it cools.
Use one as a regular bed. It offers no consistent support.
Assume a soft bed means a puncture. Check the temperature explanation first.
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 |
|---|---|
| Emma Sofa Bed | Scores 6.6. If the room needs seating the rest of the time, a sofa bed beats an air bed for regular guests, and the mattress is still shallow by necessity. |
| Simba Topper | The highest scoring topper here at 7.5. Over an air bed it insulates and spreads load, which addresses both of an air bed's problems at once. |
| Emma Original Lite | A three-zone pocket spring layer at £199, which is what the money buys if you have anywhere to keep a real mattress. |
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
Why am I cold on an air bed?
Because a large volume of air behind thin PVC is not insulation: the air circulates, carries your body heat away and loses it to the floor. Adding blankets on top does not help, because the heat is leaving downward. Put a topper or a folded duvet between you and the bed.
Why does my air bed go soft overnight without a leak?
Air contracts as it cools. A bed inflated firm in a warm room is at lower pressure once the room drops a few degrees. Inflate it a couple of hours early so the air reaches room temperature, then top it up before use.
How do I find a leak in an air bed?
Inflate it, brush soapy water over the surface and watch for bubbles. Check the valve first, because it is the commonest site, then the welded seams.
Is an air bed bad for your back?
It offers no consistent support, and pressure changes overnight as the air cools. For one or two nights that is manageable; as a regular bed it is not, and a folding mattress sleeps considerably better for similar money.
