Boxing Day mattress deals 2025: Last chance to grab these Boxing Day deals

The Nectar Memory Foam Mattress is one of the best memory foam mattresses we've tested, and it's always on sale – but now it's available for even less during Boxing Day. A single is £349, and a double is £499. We recommend the Nectar because it suits all sleeping styles, doesn't retain heat (a drawback with most other all-foam mattresses), and contours the body to relieve pressure points for fewer aches and pains. Nectar gives you a year to trial it at home to make sure it's right for you, plus you'll get a forever warranty and free and fast shipping. They are also offering half-price bedding with your mattress purchase in Boxing Day sales.

The Nectar above is ideal for people who want a more contouring mattress that gently hugs their curves. But if you want a firmer mattress that sleeps cooler and offers lots of lower back support (more than the Nectar), then the DreamCloud Hybrid Mattress is worth considering. The cost of a double is £525. It's a great hotel-style mattress without the luxury price tag, but it does take longer to break in than some other hybrids we've tested. After a couple of weeks sleeping on it, though, this is one of the best hybrid mattresses we've reviewed and an ideal choice for couples who don't know what type of bed they like.
