Layer Details
- Knitted cover. A soft knitted top layer that adds cosiness and warmth. Knitted covers are breathable, which means heat can escape rather than build up under you.
- Pillow top. An extra layer of padding sewn on top, which means a slightly more luxurious, cushioned feel when you first lie down.
- Cool Gel. A 2cm gel layer that responds to your body temperature and gently contours to your shape. It's designed to help prevent overheating through the night.
- Gel Foam. Gel-infused foam that sleeps cooler than traditional memory foam. It cushions pressure points, which can help soothe aches and pains.
- Pocket Springs. Individual springs encased in cloth pockets that move independently. This means each part of your body gets support where it needs it, and movement is less likely to disturb a partner.

- Room to stretch out alone: At 30cm wider than the UK single, the UK small double lets a solo sleeper lie diagonally or stretch an arm out without hitting the edge.
- Leaves floor space free: Being 15cm narrower than the UK double can free up the gap a door needs to swing open or a wardrobe needs to clear.
- Cooler in a snug room: The gel foam and 2cm Cool Gel layer are designed to limit overheating, which helps in a small box room or loft conversion that warms up quickly.
- Calmer nights for visiting couples: Independent pocket springs mean one guest rolling over is less likely to jolt the other awake during a weekend stay.
- Simple to furnish: The UK small double is a standard 4ft width, so you can buy frames and fitted sheets for it from ordinary bedding ranges.
This size suits you if...
You sleep alone and want more room than a UK single gives you, your bedroom is compact enough that a UK double would crowd it, or you're setting up a guest room where couples stay only now and then.
Consider another size if...
You and a partner will share the bed every night. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for the UK double.

What room size do I need for a SleepSoul Heaven 1000 small double?
We suggest allowing at least 2.4m x 2.8m for a UK small double, which leaves space to walk round the bed and open drawers. If your room falls short of that, the UK single is the better fit, and we suggest at least 2.1m x 2.8m for the UK single.
Is the SleepSoul Heaven 1000 small double long enough for tall people?
The UK small double is 190cm long, the same length as the UK single and the UK double. If your feet already reach the end of a standard bed, the UK king is 10cm longer, though we suggest at least 2.7m x 2.9m of floor space for the UK king.
Is a small double Heaven 1000 a good upgrade for a teenager?
It's a sensible step for a teenager who has outgrown a UK single. The UK small double adds 30cm of width but no extra length, so the bed takes no more room lengthways. That helps in a bedroom that still needs space for a desk and wardrobe.
Will the SleepSoul Heaven 1000 fit in a loft conversion?
The UK small double is 120cm wide, 15cm narrower than the UK double, which can make the difference where a sloping ceiling limits where you can stand beside the bed. Measure the floor area with full headroom, then compare it with our suggested minimum of 2.4m x 2.8m.
Small double or double Heaven 1000 for a guest room?
For a guest room that hosts couples only occasionally, the UK small double is usually enough and keeps more floor clear. The pocket springs limit how far one guest's movement travels. If couples visit often or stay for long spells, the UK double gives 67.5cm each and we suggest at least 2.6m x 2.8m for it.
