Layer Details
- Cover. A high-density thermal conductive fabric made from sugarcane yarn, which means excess heat is drawn away from your body as you sleep. The result is a cooler night, particularly useful in warmer months.
- Comfort layer. Soft white fibre fillings that create a cosy initial feel. They're durable and resilient, so they should hold their shape rather than flattening quickly.
- Comfort layer. Mint-infused, plant-based natural fibres that are highly breathable and antibacterial. They resist bacteria growth and add a natural cooling feeling to the sleep surface.
- Comfort layer. Advance e-Fibre filling made from recycled plastic bottles. You get a luxurious layer of comfort with a lower environmental footprint.
- Mini Pocket Springs. Small, individually cased springs sitting above the main support unit. They add comfort and soothing pressure relief while cutting down motion transfer between partners.
- Support system. 2000 e-Pocket springs providing individualised support. Each spring contours to your body shape, moulding to the areas that need it most.

- A shared bed that fits the room: At 135 x 190cm, the UK double fits comfortably where the UK king would crowd the walls, so bedside tables on both sides usually remain possible.
- Cooling matters more when you share: Two bodies raise the temperature under one duvet, and the thermal conductive sugarcane cover draws that excess heat away from you both.
- Less disturbance from a restless partner: The mini pocket spring layer reduces motion transfer, which means a partner turning over at 3am is less likely to wake you.
- 67.5cm each for two sharing: That is the standard shared allowance in a UK double, enough for most couples, slightly snug if you both sprawl.
- Easy to dress: Double sheets and a 200 x 200cm double duvet are stocked everywhere at every price, useful if you are furnishing a whole home at once.
This size suits you if...
You share the bed every night and want a proper couples' size without giving the whole room over to it, or you sleep alone and want space to stretch out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, where the cooling cover means fewer complaints from warm-sleeping guests.
Consider another size if...
You and your partner both want more personal space than 67.5cm each, or one of you is a sprawler. We'd recommend the UK king instead, which is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m of room.

What are the dimensions of the Jay-Be Bio Cool Hybrid 2000 in a UK double?
It measures 135 x 190cm, which is 4ft 6in x 6ft 3in. That is the standard UK double footprint, so any double bed frame, double sheets and a 200 x 200cm double duvet will fit it. The mattress itself is 23cm deep, on the slimmer side for a hybrid.
Is the Jay-Be Bio Cool UK double wide enough for two adults?
Two people sharing a UK double get 67.5cm each, which suits most couples. Sharing also means shared warmth, and this is where the sugarcane cooling cover and mint-infused breathable fibres help. If either of you is broad-shouldered or moves around a lot at night, the UK king gives you noticeably more space.
What room size do I need for the Jay-Be Bio Cool in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves room to walk around the bed and, in most rooms, fit bedside tables on both sides. In a second bedroom or first flat, the UK double usually still leaves space for a wardrobe.
How much bigger is the UK king than the UK double for this mattress?
The UK double is 15cm narrower and 10cm shorter than the UK king. Those centimetres matter if you're tall or you share with a restless partner, but the UK king needs a room of at least 2.7m x 2.9m by our guidance, so measure before you size up.
