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.

- Cooling that matters in small rooms: Compact bedrooms and loft conversions run warm, and the thermal conductive sugarcane cover draws heat away, which means a noticeably cooler night in a snug space.
- A slim profile for raised frames: At 23cm deep it sits lower than many hybrids, a genuine advantage on bunk, cabin and mid sleeper frames where guard rail height limits how deep a mattress can be.
- Gentle support for lighter sleepers: The retailer describes the feel as medium, with mini pocket springs adding pressure relief, so children, teens and lighter adults should sink in comfortably rather than perching on top.
- Eco credentials for a child's first big bed: Recycled-bottle fibres and mint-infused plant-based fillings give parents an easier conscience, and the hypoallergenic build helps if your child is prone to sniffles.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're furnishing a child's or teenager's room where the bed shares space with a desk and toy storage, you need a dependable guest bed for a spare room that doubles as an office, or you sleep alone in a compact bedroom, a student room or a loft conversion where only a narrow footprint fits under the slope.
Consider another size if...
You're a single adult who spreads out at night, or you want room to grow into. The UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

What size is the Jay-Be Bio Cool Hybrid 2000 UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK single, so it fits standard single bed frames, bunk beds and mid sleepers, and takes standard single sheets and a 135 x 200cm single duvet without any hunting for unusual bedding sizes.
Will the UK single Bio Cool Hybrid fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard bunk and mid sleeper frames, and the 23cm depth is slimmer than many hybrids, which helps keep the guard rail at a safe height on a top bunk. Do check your frame's maximum mattress depth before buying, as some raised frames specify a lower limit.
Is the Jay-Be Bio Cool Hybrid 2000 single a good choice for a child's room?
Yes, with a caveat on feel. The hypoallergenic fillings and recycled materials suit a child's room well, and the single footprint leaves floor space for a desk and storage. The retailer describes the feel as medium leaning soft, which most children and teens find comfortable, though a heavier teenager who prefers a firm surface may want to try before committing.
How much room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you a walkway alongside the bed and room to open a wardrobe. That makes the UK single workable in box rooms, loft conversions with a narrow flat section, and shared children's rooms where two beds need to fit with a gap between them.
Should I buy the UK single or size up to the UK small double?
For a child, a bunk frame or a tight room, the UK single is the sensible pick. If it's for an adult or a teenager staying long term, the UK small double is 30cm wider at the same length, giving welcome extra shoulder room, and needs a room of at least 2.4m x 2.8m.
