Layer Details
Pillow top
A 2cm layer of soft foam in the microquilted surface. It gives the top a softer, more cushioned feel without changing the medium to firm rating.
Cool Gel foam
A 3cm Cool Gel foam layer under the pillow top that contours to the body. It also helps disperse heat, so you get shaping with less warmth.
Pocket spring core
1000 individually pocketed springs, with 2000 mini pocket springs added for bounce and comfort. The mini springs reduce motion transfer, so you're less likely to feel a partner move.

Key benefits
- Leaves room for everything else: At 90cm wide, the UK single leaves space for a desk and wardrobe in a child's bedroom, and we suggest allowing at least 2.1m x 2.8m.
- Firm support, softer surface: SleepSoul rates it medium firm, and the 2cm pillow top cushions the surface, which means a growing child gets some give on top without losing support underneath.
- Helps in a warm small room: The 3cm Cool Gel foam layer is designed to disperse heat, which should help a solo sleeper in a box room or loft conversion that holds the day's warmth.
- Two beds for guests: Two UK singles in a guest room give visitors a bed each, and their narrow footprint makes it easier to keep a walkway clear between them.
- Familiar duvet size: A standard single duvet (135 x 200cm) fits, although the 30cm depth means you'll need fitted sheets with a deep pocket.
This size suits you if...
You're furnishing a child's or teenager's bedroom where the bed has to share space with a desk and storage, you're setting up a guest room with two beds rather than one, or you sleep alone and like medium firm support with a slightly softer surface.
Consider another size if...
You share the bed with a partner, or 90cm already feels tight when you turn over. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Will the SleepSoul Heaven 3000 UK single fit a bunk bed or mid sleeper?
Check the frame first. At 30cm deep, this is a thick mattress for a raised frame, and most bunk and mid sleeper makers set a maximum mattress depth so the safety rail stays high enough above the sleeping surface. SleepSoul doesn't publish guidance for raised frames, so compare the frame maker's limit with the 30cm depth before you order.
How much room do I need for a UK single SleepSoul Heaven 3000?
We suggest at least 2.1m x 2.8m of floor space for a UK single, which measures 90 x 190cm (3ft x 6ft 3in). That suits a box room or a loft conversion with a narrow strip of full height. Under a sloping ceiling, remember that the 30cm depth puts your head a little closer to the slope when you sit up.
Is the UK single Heaven 3000 CoolGel a good mattress for a teenager?
It suits most teenagers who sleep on their back or change position through the night, because the medium firm support stays fairly firm while the pillow top softens the surface. A very light teenager who sleeps mainly on their side may find it gives less than they'd like. If they'll want more width within a few years, look at the UK double.
Do standard single sheets fit a 30cm deep single mattress?
A single duvet (135 x 200cm) fits as normal. Fitted sheets are the part to check, because a 30cm depth needs a deep pocket to stay put at the corners. Look for the pocket depth on the packet rather than assuming any standard single sheet will do, particularly for a child who moves around a lot in bed.
Can two SleepSoul Heaven 3000 singles work in a shared kids' bedroom?
Yes, if the room has space for two beds plus a walkway. Each child gets their own 90cm wide mattress, so one turning over won't disturb the other. It can't be flipped, so you'll rotate each one using the handles; leave enough clearance at the foot of each bed, measure the room, then compare the retailers listed on this page.
