Hypoallergenic and resistant to dust mites, this mattress is perfect for those seeking a healthier sleep solution. ## Description Originally developed by the world's leading scientists at NASA, memory foam has now been adapted to provide the ultimate mattress solution. 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. ## Features - King Size 5ft x 6ft6 / 150cm x 200cm - Total Depth: 12 inch - Memory Foam Depth: 3 inch - Density: 75 kg/m3 - Comfort Rating: Medium - Firm - Includes Removable Washable CoolSoft Cover (Cover may vary from image) - Hypoallergenic, Dust and Dust Mite Resistant, Non Turn ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | HYPNIA | | Model Number | K12B-2P | | Colour | White | | Product Dimensions | 157 x 51 x 48.21 cm; 32.6 kg | | Material | Polyurethane | | Special Features | Hypoallergenic | | Item Weight | 32.6 kg | ## Images ![Hypnia 12 inch Memory Foam Mattress, King Size 5ft x 6ft6 - Image 1](https://m.media-amazon.com/images/I/71lzfBbatUL.jpg) ![Hypnia 12 inch Memory Foam Mattress, King Size 5ft x 6ft6 - Image 2](https://m.media-amazon.com/images/I/31+JxLkUhdL.jpg) ## Available Options This product comes in different **Size Name** options. ## Customer Reviews ### ⭐⭐⭐⭐ 4.0 out of 5 stars double visco mattress *by R***E on Reviewed in the United Kingdom on 20 September 2011* I purchased this mattress for my daughter she really liked it and stated it was the best nights sleep she had had for a long time. The mattress was delivered on time. It is thicker than i expected and is very comfortable to sleep on! WOUULD BUY AGAIN FROM THE COMPANY VERY GOOD SERVICE AND PRODUCT. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars If you like a firm mattress, get this *by A***M on Reviewed in the United Kingdom on 10 May 2019* We've had our 12" double for about 5 years now and it's still firm and comfortable, though it is worth pointing out that both me and my wife both prefer a firm mattress. 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 ### ⭐ 1.0 out of 5 stars Terrible Customer Service *by S***S on Reviewed in the United Kingdom on 12 January 2016* Very disappointed with this product and the seller.We purchased this mattress and were not aware that it had to be unpacked within 2 weeks to ensure it expanded fully into shape (There is no information about this on the item page). As it was a housewarming gift, it was stored in its original packaging until required (around 4 months). When we decided to open it out of the packaging in our new home, it would not expand whatsoever and was a 3inch piece of pointless crap. We contacted the seller who referred us to the 'manufacturers' website, where we found all the infortmation that we should have been provided with at the time of buying the mattress - knowing this, we wouldn't have purchased the mattress until it was needed. The seller refused to assist us in any way, knowing that the problem was due to their lack of information. We were never looking for a refund, just a replacement or any kind of assistance. Now we are left with this unusable, misshaped, piece of foam which I am now arranging to have dumped. --- ## 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.vn/products/67359837-hypnia-12-inch-memory-foam-mattress-king-size-5ft-x](https://www.desertcart.vn/products/67359837-hypnia-12-inch-memory-foam-mattress-king-size-5ft-x) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
