Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
If your child suffers from allergies, the anti-allergy design is the obvious draw here. The foam-free sprung construction means no memory foam or polyurethane layers, which some parents prefer for younger sleepers. The from-price of £135 makes it a genuinely budget-friendly option, and the EU Single size is a quietly useful inclusion if you've bought a continental bed frame, something many kids' mattresses don't accommodate. Buying through Mattressman, you'd also get free next day delivery, a 60-night trial and a 5-year guarantee, though those are the retailer's own terms rather than JAY-BE's, so check what applies if you buy elsewhere.
Key Features & what's inside
Awaiting up to date specifications. Please check back later.
Who's it NOT for?
This is a mattress designed for children, so it's not the one to pick for an adult bed, even in the Small Double size. If you like to know exactly what's inside before you buy, the available listing doesn't detail the construction layers, depth or firmness, which may put cautious buyers off.
Jay Be Simply Kids Anti-Allergy Foam Free Sprung Mattress
Does the Jay Be Simply Kids mattress come with a trial period?
Mattressman lists this mattress with a 60-night trial, confirmed in the listing's product data. That trial is the retailer's own offer rather than a JAY-BE promise, so if you buy from a different shop, check their returns terms before ordering.
How long is the guarantee on the Jay Be Simply Kids mattress?
A 5-year guarantee is included with this mattress when bought through Mattressman, according to their September 2026 listing. As it's stated on a retailer page, treat it as part of that retailer's offer and confirm the cover if you purchase elsewhere.
What sizes does the Jay Be Simply Kids Anti-Allergy mattress come in?
It's available in UK Single, UK Small Double and EU Single. The EU Single is handy if you have a continental bed frame, which standard UK mattresses won't fit properly.
How much does the Jay Be Simply Kids mattress cost?
Prices range from £135 to £199 depending on the size you choose, with the UK Single at the lower end. That's an affordable price point for a children's sprung mattress, with fewer published construction details than pricier options.
Is delivery free on the Jay Be Simply Kids mattress?
Mattressman offers free next day delivery on this mattress. That's the retailer's own delivery service, so timings and costs may differ if you buy from another stockist.
