Best mattress deals for November 2025, from Simba to Eve Sleep

I’ve tested many mattresses throughout the years, but the Simba hybrid luxe mattress has become a firm favourite. “I would go as far as to say the Simba hybrid luxe mattress has transformed my sleep, leading to an increased feeling of restfulness at bedtime,” I wrote in my review. With nine layers and just the right amount of back support, it delivers “supreme comfort”. It’s currently on sale at MyNextMattress for £1,269, which is a fair bit cheaper than buying direct from Simba (£1,699).

You can save £160 on this double mattress from Simba if you buy it from MyNextMattress. It comes IndyBest-approved and was named the best mattress for edge-to-edge support. In my review, I praised it for its six layers of “pure comfort”, with a middle layer that provides “just the right amount of bounce” and a top layer that’s “soft, breathable and hypoallergenic”. It’s a great deal, but don’t trust the original price on MyNextMattress – it’s listed as a huge discount from £1,199, but that’s much higher than the actual price on Simba’s own website (£799).

My favourite budget mattress from Dusk is now even cheaper, thanks to this deal. When you use the code “EXTRA20” at checkout, you’ll get 20 per cent off, which brings the price down to £223.20 for a double mattress. I put it to the test over the course of a year and was surprised by how comfortable it remained. The edge support is fantastic, and it has great support on pressure points, so it’s a good choice for side sleepers, I noted in my review. These discount codes don’t hang around for a long time, so you’ll need to be quick if you want to save.

If you’re on the lookout for a memory foam mattress, the original mattress from Eve Sleep has 40 per cent off in all sizes at the moment. With medium-firm support and three layers of foam, plus a moisture-wicking top cover to stop you from getting too warm or clammy, it also comes with a 200-night trial, so you have plenty of time to see if it’s right for you.
