Instead of foam, the Jay Be Pure Anti-Allergy Sprung Mattress uses Jay Be's Advance e-Fibre comfort layers, an open-structured material that lets air move through the mattress, which means it should stay cooler than a typical foam-topped design. The sleep surface is treated with plant-based margosa and linseed oils for its anti-allergy properties, and the fabric is OEKO-TEX Standard 100 certified. It comes in four UK sizes, from Single to King, and JAY-BE backs it with a 10-year guarantee. A sensible pick if allergies or overheating are your main worries.

Why should you choose this mattress?
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 an affordable starting price.
Key features & layer details
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.

Best suited for?
Allergy sufferers
The sleep surface is treated with plant-based margosa and linseed oils and the fabric is OEKO-TEX Standard 100 certified, so allergies are the main design focus.
Warm sleepers
Open-structured, foam-free Advance e-Fibre comfort layers let air circulate freely, which means less trapped heat than a typical foam-topped mattress.
Eco-conscious buyers
Plant-based anti-allergy oils replace harsher chemicals, and the e-Fibre comes from GRS-certified manufacturing, so the materials suit anyone who cares about how a mattress is made.
Budget buyers
The copy describes an affordable starting price, and the 10-year guarantee adds reassurance that the money is going towards a mattress built to last.
Back sleepers
A deep sprung core spreads support evenly across the mattress, which means your spine stays aligned rather than dropping into a dip.
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.
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 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 an affordable starting price 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.
