Best matress buying tricks today? Though technically classified as a foam mattress, the top layer of the Purple Mattress is quite different from memory foam. Dubbed the Purple Grid, this 2-inch layer of hyper-elastic polymer has large open cells like an egg crate and has a squishy, gel-like feel. The design of this grid lets lots of air flow through the mattress to minimize heat buildup, though professional testers are mixed on how cool the Purple stays at night. The Purple Mattress provides pressure relief like a foam mattress but doesn’t let you sink in quite like you will with memory foam. That’s good news for combination sleepers who like to change position at night without feeling stuck in the mattress. The Purple bed does a decent job of reducing motion transfer, so you shouldn’t feel too much jostling from a restless bedmate.

It’s certainly one of the cooler mattress experiences our testers have tried, aided by a cover that has temperature-regulating fibres, comparing well with the Original for minimising restlessness from overheating. Below the springs is a layer of pressure relieving foam, which in turn lies on a base of cold foam with cut-out technology to provide support where it’s needed most. Our testers found it quite a firm sleep, but in a supportive rather than rock hard way. It definitely took our side sleeper a few more days to get use to the fact it had less give than their usual mattress, so not the best choice for those that prefer something more cloud-like, while the back sleeper preferred it, declaring afterwards that the old mattress now felt ‘too soft, too giving’. There’s a 200-night trial period, a 10-year guarantee and hassle-free returns promise.

If you’re after a firm, supportive hybrid at a very reasonable price, look no further than this octasmart mattress. It’s the firmest hybrid we tried, although perhaps slightly less supportive than others edge to edge. But, assuming you don’t plan to cling to the side, this number is great for both side and back sleepers. The “octasprings” inside are a bit different to traditional mattress springs – they’re biodegradable for one. They also help isolate movement, and we found we weren’t woken by our co-tester getting in and out of bed. These are complemented by a layer of individual pocket springs, to give a nice bounce and firmer support. As a result, the memory foam sinking feeling isn’t quite as pronounced on the octasmart mattress as others we tried, but we were happy with that as it allowed us to move about at night without trouble. It’s a great, ache-free option for side sleepers, as there are three zoned areas on the mattress with targeted support for your back, shoulders and hips. As an added bonus, it’s 100 per cent recyclable when it comes to the end of its life.

A good mattress can transform your entire life. We know that’s a bold statement, but true. Your mattress is one of the key factors that affects your sleep, and quality of sleep. We know there is a bewildering amount of choice out there: foam, hybrid, pocket sprung, no turn, rotate. Have no fear! We’ve spent months investigating mattresses and testing them in real-world scenarios to find you the very best. Sleep is vitally important. When we sleep we give our brains and body a chance to repair, recover and process our thoughts. Good-quality sleep will improve your mood and memory as well as help to maintain overall health, weight and energy levels. And one of the most important factors affecting your sleep is your sleep environment, including your mattress. Discover even more details at https://mattressly.com/.

We tested this mattress through June and part of July, which featured heatwaves. Our reviewer was impressed at how cool the mattress kept her even in 20-degree heat – so impressive, in fact, that she slept all the way through the night. The Ultima features a removable and machine-washable thermic cover aims to reduce body temperature by two degrees. Combined with the mattress’s dynamic airflow design, it’s made to keep you cool as you sleep. The luxury element comes with the huge 10 layers in this hybrid mattress, consisting of premium memory foam and 6,000 nano and pocket springs – plus that aforementioned thermic cover. It’s important to note that this mattress is heavy – it took two pretty strong people to lug it up the stairs – but once in position, it’s easy to manoeuvre. If you want to invest in a mattress and don’t mind dropping a cool £1,000 plus, we’d really recommend this mattress. You’ll also get free premium delivery, a 100-night comfort trial and a 10-year guarantee, so you can rest assured you’re covered in case you change your mind.
