Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose the Kingfisher if you need something hard-wearing and easy to keep hygienic. The waterproof cover means accidents wipe away rather than soaking in, which means less stress for parents of young children or anyone furnishing a rental. The EcoFoam® core is made from 100% recycled and re-engineered foam, so it has a smaller carbon footprint than new foam, and it's naturally dust mite resistant with 100% synthetic, hypoallergenic materials throughout. Delivery is free next day to almost everywhere across mainland UK, although some addresses may incur a small fee. It's available in five UK sizes, from Small Single up to King, priced between £119 and £199.

Who's it NOT for?
At 10cm deep, this is a slim, no-frills mattress. If you're a heavier adult, or you want the cushioning and depth of an everyday bedroom mattress, it will likely feel too thin and too basic. It's designed for contract and practical use, not as a long-term main mattress for grown-ups.

Across 75 reviews on the MattressNextDay product page, it holds a 4.7 rating, with owners praising the quality, value for money and easy cleaning thanks to the waterproof cover. Several highlight how well it suits children who have accidents, noting it's comfortable and doesn't make noise.

Is the Kingfisher contract mattress fully waterproof?
Yes, it has a waterproof cover, which means spills and accidents can be wiped clean rather than soaking through. Owner reviews frequently mention easy cleaning and suitability for children who have accidents.
How firm is the Kingfisher waterproof mattress?
MattressNextDay describes it as medium firm. The EcoFoam® core is resilient and supportive, though at 10cm deep it will feel firmer and more basic than a full-depth mattress.
How deep is the Kingfisher mattress?
It's 10cm deep, which is slim compared with a standard bedroom mattress. That suits bunk beds, cabin beds and contract settings, but heavier sleepers may find it too shallow for everyday adult use.
Does the Kingfisher mattress come with a guarantee?
Yes, MattressNextDay offers a 5-year guarantee. The mattress is made in the UK by an NBF-Approved Manufacturer and meets the BS 7177 Source 5 fire-retardant standard.
How quickly can the Kingfisher mattress be delivered?
MattressNextDay offers free next day delivery to almost everywhere across mainland UK, although some addresses may incur a small fee.
