Best mattress deals for June 2025, from Simba to Nectar

Dreaming of a better night’s sleep? You’ve come to the right place. If you’ve been sleeping on an uncomfortable mattress for too long, I’ve handpicked the best deals from the likes of Simba, Nectar, Hypnos and more.

As The Independent’s resident sleep expert (I’ve tried and tested all the best mattresses), I make it my mission to bring you the very best offers on all sizes and types of mattresses all year round.

Mattresses are essential purchases but often come with a hefty price tag and require a little research to figure out which one will suit your sleep needs. Whether you’re after a hybrid, pocket-sprung or memory foam model, I’ve got you covered.

Keep scrolling for discounts on some of my favourite tried-and-tested brands, including savings to snap up over the bank holiday weekend.

Nectar’s hybrid mattress was chosen as the best option for medium firmness in my best mattress guide, and there’s a chunky saving to be snapped up right now. The mattress is made up of eight layers of foam, micro-springs, memory foam and a supportive base, which I found made my pressure points feel supported and spine-aligned. I also awarded it extra points for its ability to reduce motion transfer – something anyone with a wriggly sleeping partner will appreciate.

You can save £100 on this double mattress from Simba if you buy it from MyNextMattress. It comes IndyBest-approved and was named our 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 a bounce” and a top layer that’s “soft, breathable and hypoallergenic”.

If you’re looking for a supportive mattress, this could be the one for you. In tester Eleanor’s review of Otty’s hybrid mattress, she said it “undoubtedly falls on the firmer end” of the scale, describing it as a “great all-rounder that most people will find comfortable”. It’s available from Otty with a £75 discount. However, if you forgo the discount, you’ll get two of its deluxe pure pillows included. These typically cost £70 to buy separately.

When reviewing this model, I found that the Dusk hybrid “feels as luxurious as it looks”. It is “a great choice for those with back pain” owing to its firm feel and the “stellar edge-to-edge support”. Its medium firmness meant that over a year of testing, no dips or bumps developed. It’s currently reduced by £234, and you can save a further 20 per cent when you use the code EXTRA20 at checkout.

Hypnos supplies mattresses to hotels, including Soho House and The Corinthia, and it even supplies the royal family, so it’s fair to say the luxury brand doesn’t come cheap. But now, you can save nearly 25 per cent on this IndyBest-approved model with the discount code SLEEPY50. “The depth (31cm) means there are lots of layers of comfort here, including a pocket-spring system, which aids weight distribution to provide edge-to-edge support and helps to encourage better spinal alignment,” I found when reviewing it. The soft pillow top is “supportive and feels like a gentle hug.”

The IndyBest team of shopping experts have been covering sales events for many years. As a sleep expert, I track the price of mattresses year-round and know how to spot a good deal from a bad one, and I will only ever recommend a discount on a tried and tested brand. I’ve been researching the best mattress brands and testing a whole host of different options in my guide to the best, so I’m personally recommending the ones that I think are worth your money.
