Verdict
An online bed retailer with a wide range of frames, which makes it useful for the part of the purchase most mattress sites ignore. The frame decides whether your mattress guarantee survives, and that is worth as much attention as the mattress itself.
Buy it if
You are buying a frame and mattress together and you want them to arrive matched and on the same day.
Avoid it if
You want to lie on things first, or you need in-depth advice on a specific mattress.

The scores
Useful for frames, ordinary for mattresses, and good at the combination.
Competitive on frames particularly.
Broad frame selection, which is where most online mattress retailers are thin.
Clear, with own-brand lines that cannot be price-checked elsewhere.
Standard returns rather than a sleep trial on most products.
Frame and mattress arriving together is worth more than it sounds.
Online only. No shop, no lying on things.
Check the slat spacing on any frame you buy
The check that protects your mattress guarantee
Most modern mattress guarantees require slats no more than about 7.5 centimetres apart. Wider gaps are a common exclusion and manufacturers do enforce it.
Wide slats also cause the problem. The mattress sags between them, producing exactly the body impressions the guarantee would have covered.
Frame listings state slat spacing inconsistently. Ask before ordering if it is not stated, and if the answer is wider than 7.5 centimetres, budget for a slat conversion or a sheet of plywood.
This is the main reason a frame retailer deserves a page on a mattress site. The two purchases interact and almost nobody joins them up.
Buying frame and mattress together is underrated
Three practical advantages, none of which appear in price comparisons.
Sizing matches. A UK frame takes a UK mattress. If you have shopped IKEA you will know how easily that goes wrong, since a European king is 160 by 200 centimetres against a UK king at 150 by 200.
Depth is accounted for. Modern hybrids run 28 to 34 centimetres. On a frame with side rails designed for a 20 centimetre mattress, the sides end up too low to do anything. Buying together makes that visible.
One delivery. A mattress arriving before the frame means sleeping on the floor, and a frame arriving first means a room full of boxes. Coordinating two retailers is avoidable hassle.
Frames are where children's beds actually matter
Bunk beds, mid-sleepers and cabin beds are frame purchases where the specification genuinely affects safety rather than comfort.
Check guard rail height, ladder fixing, and the manufacturer's stated minimum age for the top bunk, which is typically six. Check the mattress depth limit for the top bunk as well: exceeding it raises the sleeping surface relative to the guard rail, which is the exact failure mode the rail exists to prevent.
That last one is the most commonly missed, because people buy the bed and the mattress separately and nobody mentions the limit.
A correction worth making
Commonly repeated, and wrong
Mattress guarantees are discussed entirely in terms of the mattress, and the base is one of the most common grounds for refusing a claim. Most manufacturers require slats no more than about 7.5 centimetres apart. Separately, bunk beds specify a maximum mattress depth for the top bunk, and exceeding it raises the sleeping surface relative to the guard rail. Both are frame specifications that determine whether a mattress purchase is safe or claimable, and both are routinely missed because the two items are bought separately.
Should you buy it?
Yes for frames, and particularly for buying a frame and mattress together so the sizing, depth and delivery all match.
Check the slat spacing before ordering, and if you are buying a bunk bed check the top bunk mattress depth limit. Those two numbers matter more than anything else on the listing.
Questions people ask
Does slat spacing matter for a mattress?
It is one of the most common grounds for refusing a guarantee claim. Most manufacturers require slats no more than about 7.5cm apart, and wider gaps also cause the sagging the guarantee would have covered. Ask before ordering if the listing does not state it.
Should I buy a bed frame and mattress together?
It avoids three problems. UK sizing matches, the frame accounts for modern mattress depths of 28 to 34cm rather than the 20cm older rails assumed, and one delivery means no sleeping on the floor waiting for a frame.
What should I check on a bunk bed?
Guard rail height, ladder fixing, the stated minimum age for the top bunk which is typically six, and the maximum mattress depth for the top bunk. Exceeding that depth raises the sleeping surface relative to the rail, which is the exact failure the rail exists to prevent.
