Bed Frames and Storage Beds: What Actually Matters

A bed frame is the part of the bed most people choose on looks and then blame for everything else. It decides how long your mattress lasts, whether the bed creaks at 2am, and — in a small bedroom — whether you have anywhere to put the winter duvet.
The short answer. Slats no more than 7cm apart, a centre support rail with legs on doubles and above, and solid joints. Ottoman and divan-drawer beds are the best use of floor space in a small room, and the gas-lift mechanism is the part worth paying for.
The three things that matter structurally
- Slat spacing. Gaps wider than about 7cm let a mattress bow between the slats. Over time that becomes a permanent wave in the mattress, and most manufacturers will void a warranty over it. This is the single most common way people destroy a good mattress with a cheap frame.
- A centre rail with its own legs. On anything double-size or larger, the middle of the bed carries the most load. A frame relying on side rails alone will sag in the middle within a couple of years.
- Joint type. Bolted metal-to-metal or cam-lock into solid timber stays quiet. Screws driven straight into chipboard work loose, and a loose joint is where nearly every bed creak comes from.
Sprung slats, solid slats or a divan base
Sprung (curved) slats flex under load and act as a very mild extra suspension layer. Good with foam and hybrid mattresses. The curve must face upwards — fitted the wrong way they do nothing, which happens more often than you would think.
Solid flat slats give a firmer, more predictable surface. Better under a mattress that already has all the give it needs, and the safer choice under heavier loads.
Divan bases are a fully upholstered platform, either sprung or solid-top. Sturdiest of the three, best for heavy sleepers, and the drawer options are genuinely useful. Less attractive than a frame, which is why headboards exist.
Storage beds: ottoman versus drawers
| Ottoman (lift-up) | Drawer divan | |
|---|---|---|
| Storage volume | Whole bed footprint | Two or four drawers |
| Access | Must clear the bed first | Instant, but needs side clearance |
| Works against a wall | Yes | Only if drawers are on the free side |
| Best for | Bulky, infrequent: duvets, suitcases, seasonal | Daily items: bedding, clothes |
| Failure point | Gas struts weaken over years | Runners and castors on carpet |
| Assembly | Heavier, two people | Usually delivered assembled |
One warning on ottomans: check the strut rating against your mattress weight. A pocket-sprung king can exceed 40kg, and struts sized for a light foam mattress will not hold it up. If the lid drifts down on you, that is what has happened.

Measure these before you order
- The doorway, the stairwell and the turn at the top. Divan bases in particular are rigid and large. Split-base options exist for exactly this reason.
- Clearance for drawers. A drawer needs its own depth again in free floor space to open fully. Measure from the bed side to whatever is opposite.
- Ceiling slope for ottomans. A lift-up base swings the mattress up through a large arc. In a loft room with a sloping ceiling this can be the difference between working and not.
- Total height with your mattress on. Frame height plus mattress depth. For most people, sitting on the edge with feet flat on the floor and knees at about 90 degrees is the comfortable target — roughly 55-65cm.
- Radiators, sockets and window sills along the headboard wall. Tall headboards and radiators are a common and annoying clash.
Common questions
Can I put a mattress straight on the floor?
It will support it fine, but the underside cannot breathe and you will get condensation and eventually mould between the mattress and the floor. If you must, stand it up against a wall regularly to air.
Why does my bed creak?
Almost always a joint that has worked loose, not the mattress. Tighten every bolt — including the ones you cannot see under the base — and put felt pads between any metal-on-metal contact.
Do sprung slats wear out mattresses faster?
No, they generally extend mattress life by absorbing some load, as long as the spacing is correct. It is wide slat spacing that damages mattresses, not the flex.
Is an ottoman bed hard to open with a heavy mattress?
It should not be, if the gas struts are rated for that mattress weight. Check the stated maximum before ordering, particularly with deep pocket-sprung mattresses which are heavier than they look.
Do I need a headboard?
Functionally, only if you sit up in bed — a headboard stops pillows falling off and protects the wall from head oils. Otherwise it is aesthetic.
