Layer Details
Pillow top
A cloud-like pillow top with an additional layer of adaptive memory foam and mini pocket springs, which means a soft, cushioned surface the moment you lie down. It gives the mattress that plush hotel character without you sinking straight through to the springs.
Graphite memory foam
Graphite memory foam relieves pressure as you sleep while dispersing heat away from the body. If ordinary memory foam has left you overheating in the past, this layer is designed to prevent that.
Springs
Responsive springs combining mini comfort and traditional pocket springs for enhanced support. In practice that means the mattress adapts to your shape and weight rather than pushing back in one uniform way.
Cover
A breathable bamboo cover with a silky smooth knitted surface, naturally antibacterial and hypoallergenic. A sensible choice if you have allergies or simply sleep warm.

Key benefits
- Shared space, sensible footprint: At 135 x 190cm, or 4ft 6in x 6ft 3in, the UK double leaves room for a bedside table on each side in a typical bedroom.
- 67.5cm each: Two people sharing get 67.5cm each, which is snug rather than roomy, so the medium tension and responsive pocket springs matter when you both turn over.
- Cooler for two: Two bodies make more heat than one, and the graphite memory foam and bamboo cover are designed to draw warmth away rather than trap it.
- Works as a guest bed: The plush pillow top and medium feel give visiting couples a comfortable night without either of them needing a particular firmness.
- Easy to fit in: We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m giving you comfortable space to walk round both sides.
This size suits you if...
You share the bed with a partner and want a deep, cushioned mattress without it swallowing your bedroom, or you're furnishing a guest room that couples use, or you sleep alone and like room to stretch out.
Consider another size if...
You're both tall, or you regularly wake each other up and want more personal space. We'd recommend the UK king instead; we suggest at least 2.7m x 2.9m for it.

FAQ's
Will a Sleepeezee Severn UK double fit in a small bedroom?
We suggest at least 2.6m x 2.8m for a UK double, and around 3m x 3m is more comfortable if you want to walk round both sides and keep bedside tables. If you also need a wardrobe and drawers, measure the space left for doors and drawers to open.
How much space does each person get on a Sleepeezee Severn UK double?
Two people sharing get 67.5cm each. That's enough for most couples who sleep fairly still, although it can feel close if one of you sprawls. The pocket springs respond to each person's shape and weight rather than moving as one surface, which helps when you're sleeping this near each other.
What fitted sheet do I need for a 34cm deep UK double mattress?
You need a UK double fitted sheet deep enough for a 34cm mattress, as standard sheets may not tuck under fully. Check the pocket depth on the packet before buying. For the duvet, a 200 x 200cm double is the usual choice.
How much bigger is the Sleepeezee Severn king than the double?
The UK king is 15cm wider and 10cm longer than the UK double. For two people sharing, that means the UK double gives 7.5cm less each. We suggest at least 2.7m x 2.9m for the UK king, so check your room before sizing up.
Is the Sleepeezee Severn UK double long enough for tall sleepers?
The UK double is 190cm long, or 6ft 3in. That suits most adults, but if either of you is tall enough for your feet to reach the end, the UK king is 10cm longer and would suit you better.
