Why you can trust IndyBest to find the best mattress deals
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 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 actually worth your money.
Best mattress deals March 2025
- Simba hybrid luxe mattress, king: Was £1,659, now £1,349.25, Mattressonline.co.uk
- Nectar premier hybrid mattress, double: Was £1,213, now £749,
- Eve Sleep premium hybrid mattress, double: Was £949, now £549, Evesleep.co.uk
Right now you can save a mammoth £300 on this king-size mattress from Simba. The mattress also comes IndyBest-approved, as it took the top spot in my review, where I praised the hybrid luxe for providing “decent support”, being “breathable” and “naturally temperature-regulating”.
Nectar’s hybrid mattress was chosen as the best option for medium firmness in my best mattress guide and right now there’s a whopping saving to be snapped up. It’s 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 currently save 40 per cent on Eve Sleep’s premium hybrid mattress thanks to this end-of-year saving. A fusion of spring, foam and over 1,400 full-sized pocket springs, it’s got mattress expert Ali’s seal of approval. When testing this mattress, she said: “On this, we had the best night’s sleep in years. This is thanks to the hybrid premium’s clever fusion of full-size springs and layer upon layer of innovative foam. The mattress boasts memory foam that isolates movement, meaning there’s no motion transfer if you sleep next to a night fidget – but then again, the night fidgeting seems to have ceased anyway, and we’re getting a great night’s sleep all round.”
Dormeo octasmart plus memory foam mattress, double: Was £389, now £272.30, Dunelm.com
Already a more affordable mattress, compared with many others, you can save more than £100 on Dormeo’s octasmart plus right now. Ideal if you’re in the market for a mattress-in-a-box, it comes tightly rolled and vacuum-packed for convenient and hassle-free delivery. There’s more to this model than pure ease, though. I found that it offers “a lot of bang for your buck”, with a firm and supportive design that doesn’t compromise on comfort. “As someone with occasional back and neck aches, the build gave us the support we needed, while the design’s three ‘body zones’ reduced disturbance when sharing a bed.” Tick, tick, tick.
Otty hybrid mattress, double: Was £674.99, now £599.99, Otty.com
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”. The mattress, which is made up of a 3cm layer of temperature-controlling memory foam, followed by another 3cm of high density reflex foam, and 2,000 springs, is currently on sale with nearly £100 off.
Nectar regularly earns a spot in IndyBest’s tried and tested mattress reviews. If you’re looking for a memory foam option, this deal could be the one for you. The mattress features a quilted cooling cover, pressure-relieving memory foam, and seven zone support foam, which is said to provide spinal alignment while reducing motion transfer. With more than £750 off knocked off the price of a king size mattress, now’s the time to invest in your sleep for 2025.
Dusk memory foam 2,000 pocket sprung hybrid mattress, double: Was £579, now £297,
When reviewing this model, I found that the Dusk hybrid “feels as luxurious as it looks”. It had a four-layer design and I found it to be “a great choice for those with back pain” owing to its firm feel and the “stellar edge-to-edge support”.
Hypnos pillow top elite mattress, double: Was £3,390 , now £2,180.25, Mattressman.co.uk
Hypnos supplies mattresses to hotels, including Soho House and The Corinthia, and also the royal family, so it’s fair to say the luxury brand doesn’t come cheap. But now, you can save nearly 40 per cent on this IndyBest-approved model. Earning a spot in Sarah’s tried and tested review, she said: “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.” Praising the soft pillow top, she added that “it’s supportive and feels like a gentle hug.”
Simba Earth apex mattress, double: £1,999 with free items, Simbasleep.com
Right now, you’re treated to a generous number of free items with every purchase of Simba’s Earth apex, which is one of the brand’s most eco-friendly options with zero waste and a limited production. Reviewing it in my guide to the best mattresses, I wowed at the “impressive multilayer system made of entirely natural materials, free of chemicals.” And, in terms of feel, I found it soft enough to comfortable and yet supportive enough for my intermittent back pain. In fact, “after nearly four months on this mattress, [I had] not experienced a single issue.” With each mattress purchase, you get two hybrid pillows, hybrid duvet, a performance mattress protector and summer hybrid duvet.
Our tester and parenting expert Zoe loved this mattress so much that she picked it as the number one best kid’s mattress. Zoe raved about the quality of this model, appreciating how clearly tailored to little sleepers it was. “Its soft cushioned top layer and airflow comfort layer make it incredibly comfortable for little sleepers. Meanwhile, the pocket springs provide ample support for growing bodies,” she said in her review.
