Memory foam reacts to the warmth of your body and contours to your shape in any position, supporting the areas that need it most allowing you to drift off into deep, high quality sleep. By doing this the pressure of your weight on the mattress is spread over a larger surface area which reduces pressure points and improves blood flow. Memory Foam will always remember its original shape and return to its normal size after each excellent night’s sleep.

This is what we searched for 5 years ago and we were not disappointed.I don't personally find the mattress too warm and in fact the wife usually has a hot water bottle with her most nights, even in the warmer months.We got a bargain when we bought this and in fact it was one of the deciding factors at the time but I can honestly say it was the best money I've spent. We're in the process of buying a new bed and we almost decided on a king size so would have bought the king mattress, but we eventually settled back on the double so it'll be around for a while yet.I've not lost its shape or firmness, though it would be interesting to try a new one side by side, but I've not noticed enough change that I've thought about replacing it.We'd bought an £800 mattress from the store prior to this one and only lasted a few years before it turned into porridge and became uncomfortable.In short:I recommend this mattress if you prefer a firm one.I would buy another if I needed oneThey are great value for money but you will need to buy deep fitted sheets, now more widely available that 5 years ago ### ⭐⭐ Like sleeping in an oven. *by I***S on Reviewed in the United Kingdom on 6 October 2014* It seems that you are likely to either love or hate this mattress, based on my own and other users' experiences.My wife and I went for this Hypnia model, as it seemed to be offered at a good price and most reviews were positive. This is what we have found:-1) The smell after unpacking lingered for several weeks and gave us sore throats.2) Two free memory foam pillows were supplied with the mattress: one had a stained cover and there was no reply from the manufacturer when they were informed of the defect.3) The mattress feels comfortable when first getting into bed, but once the foam has compressed, it is difficult to turn over or change position. On a positive note, if one of us gets up during the night, it doesn't disturb the other.4) The worst aspect is that the mattress is far too warm: we are always having to fling the covers off to cool down. I know this is a personal thing, but if you like a cool bed, then please be aware. My wife can't get a decent night's sleep because of the heat. Even in winter, I sweat buckets and this has stained the supposedly washable cover. The washing instructions state: wash at 30 degrees and do not use detergent. Just what are you supposed to use to clean it properly?Having suffered enough discomfort, we have now purchased a conventional pocket-sprung mattress (which can also be turned over, unlike the Hypnia). I suppose that the Hypnia could come in handy for making car-washing sponges, if it can't be sold second-hand. ### ⭐⭐⭐⭐⭐ Comfy and inexpensive *by A***R on Reviewed in the United Kingdom on 11 August 2011* We've had it for one week now. It arrived within 2 days of ordering in a heavy but not huge box. Once expanded, it is a really big (deep) mattress. The smell disappeared after 2-3 days and is incredibly good to sleep on. The pillows are good as well - but too small to fill any normal pillow cover.I've got a dodgy lower back and can suffer badly from a sprung mattress. This mattress is very comfortable and supports all the parts of the body during sleep. The price is much cheaper than most of the others I'd seen - so was a bit dubious when I ordered it but I'm very pleasantly surprised so far. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/61667320-hypnia-12-inch-memory-foam-mattress-double-size-4ft6-x](https://www.desertcart.vu/products/61667320-hypnia-12-inch-memory-foam-mattress-double-size-4ft6-x) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-19*
