Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
The main draws here are the pocket sprung construction and the anti allergy design, a sensible pairing for a child's room where dust and spills are facts of life. If you buy from Mattressman, they list a 60-night trial and free next day delivery, useful if you need the bed sorted quickly, although those are that retailer's own terms rather than Jay-Be's. The 5-year guarantee, however, comes as standard from Jay-Be itself. At £175 to £239 it sits in sensible territory for a children's pocket sprung mattress, and the EU Single option is a quiet bonus if you've bought a continental frame.
Key Features & what's inside

Who's it NOT for?
There's no double or king option, so it won't suit adults or shared beds. The product page doesn't detail firmness or materials, which makes it a slightly harder pick if your child has a strong preference for a soft or firm feel, or if you need specific certifications confirmed before buying.

What sizes does the Jay Be Simply Kids mattress come in?
It's available in UK Single, UK Small Double and EU Single. The EU Single is handy if you have a European-sized children's bed frame, which standard UK mattresses won't fit properly.
Does the Jay Be Simply Kids mattress have a trial period?
Mattressman lists a 60-night trial with this mattress. That's the retailer's own offer rather than a Jay-Be policy, so if you buy elsewhere, check that seller's returns terms before ordering.
How long is the guarantee on the Jay Be Simply Kids mattress?
Jay-Be provides a 5-year guarantee as standard from the manufacturer, which should comfortably cover the years a child is likely to use it before sizing up.
How much does the Jay Be Simply Kids Pocket Sprung mattress cost?
Prices run from £175.00 up to £239 depending on the size you choose. It's currently listed with one retailer, so there's little scope for comparing prices across shops.
