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.

- Space to spread out: At 75cm each, the UK king gives you 7.5cm more personal space than the UK double, which means fewer nights clinging to the edge or dodging an elbow.
- Fewer early-morning wake-ups: Independent pocket springs, plus the extra width of the UK king, mean a partner slipping out hours before you is less likely to jolt your side of the bed.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, so a partner over six foot can stretch out without their feet hanging off the end.
- Room for a four-legged guest: If the dog sleeps on the bed every night, the 15cm of extra width over the UK double gives it a spot to curl up without taking over your half.
- Fits most main bedrooms: We suggest a room of at least 2.7m x 2.9m, which is less floor space than the UK super king asks for while still giving two people proper room.
This size suits you if...
You share the bed every night and a double has started to feel cramped, one of you rises much earlier than the other and you want less disturbance, or one partner is tall enough that a 190cm mattress leaves their feet close to the edge.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Is the SleepSoul Heaven 1000 king size big enough for two adults?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more each than the UK double. If you both sprawl, or a child or dog regularly joins you, the UK super king gives 90cm each, although that means 15cm less each on the UK king by comparison.
SleepSoul Heaven 1000 UK king or super king for couples?
The UK king is 30cm narrower than the UK super king, but the two are the same length. Choose the UK king if your room is tight, as we suggest at least 2.7m x 2.9m. The UK super king needs at least 3m x 2.9m, so measure your room carefully before sizing up.
Is the SleepSoul Heaven 1000 in a UK king long enough for someone over six foot?
It gives you more leeway than the smaller sizes. At 200cm, the UK king is 10cm longer than the UK double, the UK small double and the UK single. If you're tall, the extra length makes more difference than the width. The UK super king adds no further length, so there's no need to size up for height alone.
What size bedroom do I need for a SleepSoul Heaven 1000 king?
We suggest a room of at least 2.7m x 2.9m for the UK king. New build master bedrooms can feel a little smaller once fitted wardrobes are in, so measure the clear floor space rather than the total room size. If you come up short, the UK double needs at least 2.6m x 2.8m.
Will my partner's movement wake me on the SleepSoul Heaven 1000 UK king?
It's less likely than on a narrower size. The pocket springs work individually, which means movement stays close to where it starts, and at 75cm each the UK king gives you slightly more distance from your partner than the UK double does. Light sleepers on very different schedules may still notice some movement.
