Assessed from JAY-BE's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Two things set this mattress apart at its price. First, it's completely foam-free: the comfort layers use breathable Advance e-Fibre with an open structure that allows air to circulate freely, which means less of the trapped heat that foam mattresses can suffer from. Second, the anti-allergy approach is plant-based, using margosa and linseed oil treatments rather than harsher chemicals, and the mattress uses a salt-based fire retardant treatment too. Jay Be also lists free next working day delivery when you order before 12pm, and the brand holds ISO certifications for environmental management, quality and health and safety, with GRS-certified manufacturing for its e-Fibre. The 10-year guarantee is reassuring at a from-price of £259.
Key Features & what's inside
- Sleep surface. A soft-knitted sleep surface treated with plant-based margosa and linseed oils, which is where the anti-allergy protection comes from. It sits directly against your bedding, so the treatment works where it matters.
- Comfort layer. Extra-soft Advance e-Fibre, deep-quilted for gentle cushioning. This gives the initial softness you feel when you first lie down.
- Comfort layers. Breathable, 100% foam-free open-structured comfort layers that allow air to circulate freely. If you tend to sleep hot, this is the layer doing the work to keep you cooler.
- Support core. A deep sprung core that distributes support evenly across the mattress. This is what keeps your spine aligned rather than letting you sink into a dip.

Who's it NOT for?
At 21cm deep with a medium feel, this isn't the mattress for anyone wanting a plush, sink-in sensation or a very firm orthopaedic feel. Heavier sleepers may find the shallower profile offers less depth of cushioning than a taller hybrid, and there's no memory foam contouring here at all, deliberately so.

Is the Jay Be Pure Anti-Allergy mattress foam free?
Yes. The comfort layers are 100% foam-free, using Jay Be's open-structured Advance e-Fibre instead, which allows air to circulate freely through the mattress. That makes it a good option if you want to avoid foam for temperature or allergy reasons.
How firm is the Jay Be Pure Anti-Allergy sprung mattress?
Jay Be describes it as medium firmness. That suits most sleepers, although anyone who prefers a very soft, cushioned feel or a distinctly firm surface may want to look elsewhere.
What makes the Jay Be Pure mattress anti-allergy?
The soft-knitted sleep surface is treated with plant-based margosa and linseed oils. The fabric is also OEKO-TEX Standard 100 certified, and the mattress uses a salt-based fire retardant treatment rather than harsher alternatives.
What guarantee comes with the Jay Be Pure Anti-Allergy mattress?
Jay Be lists a 10-year guarantee on this mattress, which is generous at this price point and suggests some confidence in the sprung core's durability.
What sizes does the Jay Be Pure Anti-Allergy mattress come in?
It's available in UK Single, Small Double, Double and King, priced from £259 to £339 depending on the size you choose.
