Best bed frames
A bed frame is the cheapest way to ruin an expensive mattress, and slat spacing is how it happens.
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 number that matters
Most modern mattress guarantees require slats no more than about 7.5 centimetres apart. Wider gaps are a common exclusion, and they also cause the problem: the mattress sags between the slats, producing exactly the impressions the guarantee would have covered.
That single specification matters more than the material, the style or the brand. A frame with wide slats will destroy a good mattress and leave you unable to claim for it.
The rest is practical: a centre rail with a supporting leg on anything double or larger, a height that suits you once the mattress is on, and a construction method that will survive being moved.
The picks
The pick, if you want one answer
Origin Timber Bed Frame, 7.6 / 10. Solid timber with proper slat spacing and a construction that can be taken apart and reassembled without losing rigidity.
| Product | Best for | From | Score |
|---|---|---|---|
| Origin Timber Bed Frame | Best overall | Mid range | 7.6 / 10 |
| Origin Storage Bed Frame | Best with storage | Mid range | 7.5 / 10 |
| DreamCloud Bamboo Bed Frame | Best design-led option | Mid range | 7.4 / 10 |
| Simba Bed Frame | Best for a boxed mattress setup | Mid range | 7.3 / 10 |
Origin Timber Bed Frame: Best overall
Mid range · 7.6 / 10
Scores 7.6. Solid timber with sensible slat spacing, and the construction matters more than it sounds: a frame assembled with bolts into timber holds rigidity far better through repeated disassembly than cam lock fittings, which loosen in the same hole each time.
Buy it if
You want solid timber construction that will survive house moves.
Do not buy it if
You need storage. Look at an ottoman instead.

Origin Storage Bed Frame: Best with storage
Mid range · 7.5 / 10
Scores 7.5. Drawer storage is easier to use daily than a lifting platform, because you are not moving the mattress to reach anything. The trade is capacity and, on carpet, that drawers need clearance to run.
Buy it if
You want storage without the weight and mechanism of an ottoman.
Do not buy it if
You need to store bulky items. Drawer storage is shallower than an ottoman cavity.

DreamCloud Bamboo Bed Frame: Best design-led option
Mid range · 7.4 / 10
Scores 7.4. Worth knowing that bamboo in furniture is genuinely bamboo, unlike bamboo in bedding where it is almost always bamboo viscose, a chemically regenerated fibre. Here the word means what it appears to mean.
Buy it if
You want something that looks considered and still meets the spacing rule.
Do not buy it if
You want the most robust possible construction.

Simba Bed Frame: Best for a boxed mattress setup
Mid range · 7.3 / 10
Scores 7.3. The useful thing here is that the frame and the mattress are designed to the same depth assumptions, which removes the most common mismatch: a deep hybrid on a frame designed around a 20 centimetre mattress puts the surface far higher than expected.
Buy it if
You are buying a boxed mattress and want a frame designed around the same depth.
Do not buy it if
You have an unusually deep mattress. Check the finished height.

Four measurements before you order
1. Slat spacing. No more than about 7.5 centimetres. If you already own a frame, measure the gaps rather than counting slats. Too wide is fixable: a slat conversion kit, or a sheet of plywood cut to size, costs a few pounds against an unclaimable mattress.
2. Finished bed height. Add the frame deck height to the mattress depth. Modern hybrids run 28 to 35 centimetres. Aim for 55 to 65 centimetres floor to mattress top, so your feet reach the floor with your knees at roughly a right angle when sitting on the edge.
3. The room, including the door. Measure the path in, not just the space it will sit in. A king frame in flat pack is manageable; an assembled one is not.
4. The mattress size, in UK terms. A UK double is 135 by 190 centimetres, a European double is 140 by 200. They are not interchangeable and imported frames catch people out.
Construction, and why it matters at the second house move
| Method | What to expect |
|---|---|
| Bolts into solid timber | Holds rigidity through repeated assembly. The best outcome. |
| Cam lock fittings | Fast to assemble, and the fitting loosens in the same hole each time. Common in flat pack. |
| Metal frame, bolted | Rigid and light, and prone to squeaking where metal meets metal. |
| Upholstered on a timber frame | Quiet and warm, and you cannot inspect what is underneath. |
A squeaking bed is almost always a joint that has loosened rather than a broken part. Tightening every bolt and adding a nylon washer where metal contacts metal fixes most of them.
The centre rail is not optional
On a double or larger, the middle of the frame is where sagging starts, because it is furthest from any support and carries the most load.
A centre rail with at least one supporting leg to the floor is what prevents that. Some frames sell it as an upgrade, and on a king or super king it is structural rather than optional.
If you are heavier, or two of you share, treat two centre legs as the sensible specification.
Slatted, solid or sprung base
Slatted is the standard and suits almost every modern mattress, provided the spacing is right. Sprung slats flex slightly and add a little give.
A solid platform supports evenly and blocks airflow underneath, which matters with foam mattresses and in damp rooms, where condensation can form against the underside.
A sprung divan base is part of the system with many hand-built mattresses, and the manufacturer will say so. It is not an upsell in that context.
What not to buy
A frame with slats more than about 7.5 centimetres apart. The single most expensive mistake in this category.
A double or larger without a centre rail and leg.
A frame chosen before checking the finished bed height.
A European-sized frame for a UK mattress. A UK double is 135 by 190cm, a European double 140 by 200.
A solid platform under a foam mattress in a damp room, without accepting that you will need to lift and air it periodically.
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 Original Bed Frame | Scores 7.0. A sound frame, and the ones above it offer better construction or storage for similar money. |
| Emma Sofa Bed | Scores 6.6. A different product for a different job. Sofa beds compromise on mattress depth by necessity, so judge them as occasional beds. |
| Emma Ottoman Bed | Scores 7.3 and a good ottoman. Covered separately, because ottoman bases raise questions about gas struts and mattress weight that a slatted frame does not. |
| DreamCloud Ottoman | Scores 7.1. Same category note as above: check the strut rating against the actual weight of your 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
How far apart should bed slats be?
No more than about 7.5 centimetres. Most modern mattress guarantees require it, wider gaps are a common exclusion, and they also cause the sagging the guarantee would have covered.
Can I fix a bed frame with slats too far apart?
Yes, and cheaply. A slat conversion kit or a sheet of plywood cut to size costs a few pounds, against a mattress you cannot claim on.
Does a double bed need a centre rail?
Yes, with at least one leg to the floor. The middle of the frame is furthest from support and carries the most load, which is where sagging starts. On a king or super king it is structural rather than optional.
Why does my bed frame squeak?
Almost always a joint that has loosened rather than a broken part. Tighten every bolt and add a nylon washer where metal contacts metal.
