Layer Details
Pillow-top layer
A 2cm layer of soft foam in a quilted pillow-top cover. It gives the surface a plush, cushioned feel, so the mattress feels softer on top than the medium soft rating alone suggests.
CoolGel layer
A 3cm layer of CoolGel foam that SleepSoul says slows down heat build-up in the mattress. That should help you stay more comfortable through the night if you tend to sleep warm.
Mini pocket springs
An extra layer of 1200 mini pocket springs. They add comfort and support just beneath the foam, so the surface responds to your body more closely.
Pocket spring base
800 pocket springs that SleepSoul says conform to your body's shape. They support you where you need it most and form the main support in the mattress.

Key benefits
- More room each: Each sleeper gets 75cm, which is 7.5cm more each than a UK double, so an early riser can get up without reaching across a partner's half.
- Length for taller sleepers: At 200cm long (6ft 6in), the UK king is 10cm longer than the UK double, which means taller feet stay on the mattress instead of over the end.
- Cushioning on both halves: The medium soft pillow top eases pressure at shoulders and hips for side sleepers on each side, although a heavier partner may find it gives a little too much.
- Help for a warm shared bed: If one of you runs hot, the 3cm CoolGel foam layer is there to slow heat build-up, which helps when two people share the same surface.
- Fits more rooms than a super king: We suggest at least 2.7m x 2.9m for the UK king, against 3m x 2.9m for the UK super king, so it suits many standard master bedrooms.
- Easy bedding: Standard UK king sheets fit, and a 230 x 220cm king duvet gives you both enough to tuck in without a nightly tug of war.
This size suits you if...
You share the bed every night and one of you gets up hours before the other, a tall partner's feet hang off your current UK double, or you're both side sleepers who want a cushioned surface with more space to shift position.
Consider another size if...
Your bedroom measures less than 2.7m x 2.9m once wardrobes and drawers are in. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the SleepSoul Heaven 2000 king size big enough for two adults?
For most couples, yes. The UK king gives 75cm each, which is 7.5cm more each than the UK double. If you want more space between you still, the UK super king gives 90cm each, so the UK king gives 15cm less each than that.
Is a UK king SleepSoul Heaven 2000 long enough for a tall person?
It's 200cm long, or 6ft 6in, which is 10cm longer than the UK double and the UK single. The UK super king is the same length, so if length is your only concern, the UK king gives you the extra room without the wider footprint.
What size bedroom do I need for a SleepSoul Heaven 2000 UK king?
We suggest at least 2.7m x 2.9m, with around 3.2m x 3.2m being comfortable. New build master bedrooms can feel smaller once fitted wardrobes are in, so measure the floor you actually have left, including space to walk round both sides.
Should I get the SleepSoul Heaven 2000 in a king or super king?
Choose the UK king if 75cm each suits you and your room is tight: we suggest at least 2.7m x 2.9m. The UK super king is 30cm wider, gives 90cm each and needs at least 3m x 2.9m by our guidance. Both are 200cm long.
What bedding fits a SleepSoul Heaven 2000 king size mattress?
Standard UK king bedding fits the 150 x 200cm mattress, and a 230 x 220cm king duvet covers two people comfortably. The mattress is 30cm deep, so check that any fitted sheet you buy is made for that depth before ordering.
