Layer Details
- Knitted Cover. A soft knitted cover that is removable and machine washable, which makes it easy to keep fresh. It's also highly breathable, helping air move away from your body overnight.
- EcoFoam®. A unique material made from 100% recycled and re-engineered foam, designed to be resilient and durable with excellent body support. It's naturally dust mite resistant, a plus if you're prone to allergies.

- Real room for one: At 120cm wide, the UK small double is 30cm wider than the UK single, which means a solo adult can sprawl rather than sleep in a straight line.
- Fits where a double won't: It's 15cm narrower than the UK double, often the difference between a door that opens fully and one that catches the bed frame in a box room or studio.
- Same length as a single: The UK small double and the UK single are the same length at 190cm, so upgrading a teenager's bed adds width without eating extra floor along the wall.
- Light enough to shift: The slim 14cm foam build makes this size manageable up narrow stairs or into a loft conversion, where a heavier sprung double is an awkward carry.
- A sensible guest room spec: Occasional couples can share a small double for a night or two, and the firm EcoFoam® core paired with a washable cover suits a bed used in bursts.
This size suits you if...
You sleep alone and have outgrown a UK single but can't spare the width a UK double demands, you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or you're fitting a bed into a box room, studio or loft conversion where every centimetre of floor decides whether the room still works. Allow at least 2.4m x 2.8m of floor space.
Consider another size if...
You and a partner will share this bed every night, in which case a firm mattress at this width will feel tight. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

Is a small double big enough for two adults every night?
For occasional stays, yes, which is why this size suits guest rooms. For nightly sharing it's a squeeze, especially on a firm mattress where neither of you sinks toward the middle. The UK double gives 67.5cm each for two sharing, and we'd suggest that as the minimum for couples using the bed full time.
What room size do I need for the Value Eco Foam small double?
We suggest allowing at least 2.4m x 2.8m of floor space. That leaves enough clearance to walk round the bed and open drawers or doors. If your room is tighter than that, the UK single would suit you better; we suggest at least 2.1m x 2.8m for that size.
Is the small double a good upgrade from a single for a teenager?
Yes, and it's one of the most common reasons people buy this size. The UK small double is 30cm wider than the UK single but exactly the same length, so the bed grows sideways only. The firm feel and washable cover also make sense for a teenager's room, though very light side sleepers may find it a little unforgiving.
Will this size fit in a loft conversion or box room?
Often, yes. At 120cm wide it's 15cm narrower than a standard UK double, which can be the margin that leaves standing room beside the bed under a sloped ceiling. The slim 14cm foam construction also makes it far easier to carry up a tight loft staircase than a full-depth sprung mattress.
Is the small double easy to find bedding and frames for?
Yes. The 4ft small double is a standard UK size, so fitted sheets and frames are widely available. Use small double fitted sheets with a standard double duvet. That's handy if you're kitting out a rental or holiday let, where replacing linen quickly matters more than it does at home.
