The importance of a good night's sleep cannot be overstated, with research indicating it can enhance mood, concentration and the immune system. With this in mind, we've spotted an excellent early Black Friday sale that makes upgrading our sleep setup easier and more affordable. REM-Fit's early sale event, which runs until 31 October, offers up to 10% off mattresses when shoppers use the code EARLYBIRD10 at checkout. This code can be used in conjunction with existing discounts, meaning double-sized mattresses now start from just £373. As if that wasn't enticing enough, every mattress purchase includes free bedding accessories worth up to £247. This includes a pair of memory foam pillows valued at £99 . For those unsure where to begin, our top recommendation is the 1000 Pocket Hybrid mattress . Currently reduced to £413.99 from £449.99, the discount code brings the price down even further to £372.59. This medium-firm mattress combines 1,000 pocket springs with a breathable open-cell foam layer, helping to regulate temperature throughout the night. It's designed with zoned tensions to alleviate pressure-point build-up and motion isolation - fantastic news for anyone who shares a bed with a restless partner, reports the Mirror . There's even an optional old mattress removal service, allowing customers to upgrade without the inconvenience of disposing of their old one. Plus, there's a 15-year full replacement guarantee. Alternatively, there are other REM-Fit mattresses to consider. The 600 Lux Elite Hybrid Mattress is currently on offer at £809.99, down from £899.99 for a double, and features zoned memory foam for targeted support and alignment. The 500 Ortho Hybrid Mattress , reduced to £597.99 from £649.99, is a firm-tension design that can help with back pain and those who need more support. It also boasts the same breathability technology as REM-Fit's other mattresses. But REM-Fit isn't the only bedding brand offering great options. Simba is another mattress choice, with its popular Hybrid Mattress priced at £799 for a double, which has garnered over 100,000 five-star reviews for its 'supportive' five-layer structure. Emma Sleep could also be the answer for those seeking comfort during their slumber. Its Hybrid Premium Mattress is priced at £224.10 for a double and is stacked with three layers of advanced foam that target essential sleep factors, making the mattress more breathable, supporting even weight distribution, and reducing motion transfer. Returning to REM-Fit , the 1000 Pocket Hybrid mattress has received plenty of positive reviews on Trustpilot. One shopper said: "After weeks of researching and searching through many different companies and mattress types, I finally went for the plunge and purchased the REM-Fit Hybrid Pocket 1000 Mattress, king size. "We have now had this for over three weeks, and sleep has been so much better, and it has reduced my lower back pain. I sleep on my front and back, whilst my husband is a side sleeper, and this mattress is good for all sleeping positions. Would definitely recommend." A second person added: "I couldn't be happier with my RemFit Prime 1000 mattress! It's unbelievably soft and spongy – I sink right into it. It honestly feels like I'm sleeping on a luxury hotel bed every single night. It has that high-end, premium feel but at a fraction of the cost, which makes it even better." However, there have been some delivery issues. One customer noted: "Delivery window kept getting longer as the day went on, but delivered eventually on the day arranged." On a more positive note, a fan of the 1000 Pocket Hybrid mattress shared: "The REM-Fit Hybrid Pocket 1000 is the Mattress I've been searching for. I have been looking into the REM-Fit Hybrid Pocket 1000 Mattress for some time now, and after buying it, I'm not disappointed. "I love my mattress! It's comfortable and supports my back. I feel rested after a night's sleep. It's the best mattress I've ever bought."
