      The solution to hot, sleepless nights, the SleepSoul Cooler Ortho 4000 Series Pocket Gel Mattress is here to keep you cool and comfortable all night long. With thick layers of cool gel memory foam, you'll instantly feel the cooling effects of this refreshing mattress as soon as you touch it!

      Orthopaedic support for better posture

      Firm pocket springs keep your body wonderfully supported, with orthopaedic effects. By moving independently, these springs are able to precisely target your pressure points, keeping your spine, hips, and shoulders perfectly aligned. Memory foam layers provide further support by cushioning your body and molding to your unique curvature. This breathable foam responds to your movements, ensuring you're properly supported and comforted at every point of contact.

      Actively draws heat away from your body

      Generous layers of thick cool gel memory foam also cushion your pressure points, but their most exciting feature is the cooling sensation they provide. Actively drawing heat away from your body, this specially engineered material prevents overheating and encourages a night of deeper sleep, with your body naturally dropping in temperature as you sleep. It's well-known that coolness can help to reduce inflammation, so coupled with orthopaedic support, this mattress encourages a truly blissful night's sleep.

      Instant cooling sensation

      A cool feel knitted fabric cover enhances breathability, as well as offers an instant cooling effect as soon as you get into bed. This incredible technology is impressively cool to the touch, not just drawing excess heat away from your body, but actively emitting a cold sensation to refresh your entire body. Perfect for hot sleepers, those going through menopause, or anyone who enjoys a cooler sleeping environment, this cover provides fast-acting freshness.

      So far so good! the cooling is good and the mattress feels firmer than the photos suggests, which is good. The rolled option means that I could bring it to my room without issues.

      I had the best sleep with no more back pain since I used this matress. Superb quality. Better than those branded and expensive ones.

      I needed a firm and supportive mattress, and this is exactly it. After a week we got used to it, and now it even feels softer than in the first days. If youre looking for a firm mattress this is the one!

      Once the mattress had fully expanded after the vacuum package it is exceedingly comfortable. It was over a hundred pounds cheaper than a mattress I bought last year but a hundred times better quality and comfort.
