The Jay-Be Bio Cool Hybrid 2000's fillings lean heavily on sustainable materials: a sugarcane yarn cover that conducts heat away from your body, mint-infused breathable fibres, and Advance e-Fibre made from recycled plastic bottles, which means a cooler, cosier feel with an eco-friendly story behind it. It's hypoallergenic, handcrafted in the UK, and comes from a National Bed Federation approved brand. It comes in four UK sizes at a price that's good value for a 2000-spring hybrid with so much cooling technology.

Why should you choose this mattress?
If you're a hot sleeper, this is where the Bio Cool makes its case. The thermal conductive sugarcane cover draws excess heat away, and the mint-infused fibres add breathability along with a natural antibacterial quality, which means you should feel noticeably cooler than on a standard fibre-topped hybrid. Support comes from 2000 individually cased e-Pocket springs that contour to your body, with a layer of mini pocket springs above them for pressure relief and reduced motion transfer, useful if you share a bed with a restless partner. The recycled-bottle fillings will appeal if sustainability matters to you. A 10-year guarantee is retailer-listed, and Mattress Online offers a 100-night comfort trial, subject to buying a mattress protector from them.
Key features & 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.

Best suited for?
Warm sleepers
A sugarcane yarn cover draws heat away from your body and mint-infused fibres add breathability, which means a noticeably cooler surface through the night.
Couples
A layer of mini pocket springs sits above the main support unit and cuts down motion transfer, so a restless partner is less likely to wake you.
Eco-conscious buyers
Advance e-Fibre made from recycled plastic bottles and a sugarcane yarn cover give this mattress a lower environmental footprint than a standard fibre-filled hybrid.
Allergy sufferers
The mattress is described as hypoallergenic, and its mint-infused natural fibres resist bacteria growth, which makes it a sensible pick if you react to bedding.
Side sleepers
A soft feel, soft fibre fillings and 2000 e-Pocket springs that contour to your body should let shoulders and hips sink in comfortably.
The retailer page describes this as medium, so if you sleep on your front or you're a heavier build who prefers a properly firm surface, it may feel a little soft for you. And if you want a traditional deep-feeling mattress, the 23cm profile is on the slimmer side.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Jay-Be Bio Cool Hybrid 2000 soft or medium?
The product page lists it as medium, although you may see it described as soft elsewhere. Medium is the wording to trust here: a balanced feel that suits most back and side sleepers, though lightweight side sleepers wanting a plush sink-in surface might prefer something softer.
Does the Jay-Be Bio Cool Hybrid come with a trial?
Mattress Online lists a 100-night comfort trial on this mattress. It's the retailer's own offer rather than a Jay-Be guarantee, and eligibility requires buying a mattress protector from Mattress Online, so check the terms if you buy elsewhere.
How long is the guarantee on the Jay-Be Bio Cool Hybrid 2000?
The retailer listing shows a 10-year guarantee, which is a reassuring span for a mattress with a mid-range starting price.
Is the Jay-Be Bio Cool Hybrid good for hot sleepers?
It's built for them. The sugarcane yarn cover conducts heat away from your body, and the mint-infused fibres are highly breathable with a natural cooling feeling, so warm sleepers should notice a genuine difference compared with a standard fibre-topped mattress.
What sizes does the Jay-Be Bio Cool Hybrid 2000 come in?
It's available in UK Single, Small Double, Double and King.
