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.

- Leaves room for everything else: We suggest at least 2.1m x 2.8m of floor space for a UK single, which means a desk and wardrobe can still fit in a small bedroom.
- Support that follows a restless sleeper: The pocket springs move independently, which means a child or teenager who shifts about all night gets support where their body presses down.
- Helps a warm box room stay comfortable: The 2cm Cool Gel layer is designed to stop heat building up under you, which helps in a compact bedroom that warms quickly with the door shut.
- Two beds for guests who aren't a couple: A pair of UK singles in a spare room lets friends or siblings sleep separately, and they can be pushed together for a couple, with a slight gap down the middle.
- Check raised frames before ordering: At 25cm deep, this mattress needs a bunk or mid sleeper that allows that depth, so the safety rail still sits high enough above the sleeping surface.
This size suits you if...
You're buying a bed for a child or teenager whose room also has to hold a desk and storage, or you're setting up a spare room where two separate beds will get more use than one larger one.
Consider another size if...
You're an adult who likes to spread out, or someone sometimes shares the bed with you. We'd recommend the UK small double, which is 30cm wider; we suggest at least 2.4m x 2.8m for it.

Will the SleepSoul Heaven 1000 UK single fit a mid sleeper or cabin bed?
It will fit the standard 90 x 190cm footprint, but depth is the real question. This mattress is 25cm deep, so check the maximum mattress depth your frame's maker allows. On a raised bed the safety rail needs to sit well above the mattress surface, and a deep mattress can reduce that margin.
Is a UK single SleepSoul Heaven 1000 big enough for an adult?
For one adult who sleeps fairly still, yes. It measures 3ft x 6ft 3in, so most people fit lengthways. Taller adults may prefer the UK king, which is 10cm longer than the UK single, although that is a much bigger bed for a small room, and we suggest at least 2.7m x 2.9m for it.
How much room do I need for a UK single Heaven 1000?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves space to get in and out comfortably and to open drawers or a wardrobe nearby. In a loft conversion, measure the flat floor area under the slope rather than the full room, since you'll want to sit up without hitting the ceiling.
Can I fit two SleepSoul Heaven 1000 singles in a shared or guest room?
Often, yes, and it's a common setup for siblings or guests who don't share a bed. Each mattress is 90 x 190cm, so measure your room with both beds and a walkway between them marked out on the floor before you order. Two firmness-matched mattresses also mean neither sleeper ends up on a noticeably different feel.
Should I buy a UK single or a UK small double for a teenager?
A UK single fits more easily and keeps floor space for a desk. The UK small double is 30cm wider and the same length, which gives a growing teen more room to sprawl. For the UK small double, we suggest at least 2.4m x 2.8m, so it only makes sense if the bedroom can take it.
