Hypnia 12 inch Memory Foam Mattress, King Size 5ft x 6ft6

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.

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

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.

10 yr waranty but after 12 months use the foam has conciderably softened leaving impression saggin in mattress used with a 14 stone person

Great price. Well packaged. Arrived on time. All good so far.The memory foam mattress arrived on time.The mattress arrives vacuum sealed and rolled up for easy transport. Easily 4 or 5 times more compact than when unwrapped.The experience of opening the mattress from its plastic shell is great. It starts to draw air into the sponge and starts to grow straight away.We let the mattress settle for a couple of days. Noticed no manufacturing smells after a couple of days at all.The mattress grows to quite a thick size and was just right for our new leather bed.Mattress feels firmer than I thought it would.The soft cotton feel material covering the mattress amd pilows feels nice.You do get that "as seen on tv" effect when you push your hand into the mattress and pull it away you can see your hand print where the material has conformed to the shape of your hand and it slowly fills out. Sweet.If your used to sprung mattresses it takes a bit of getting used to. I tend to toss and turn at night its not so easy as its not spring assisted!After one night noticed that lower back twinge is not present in new mattress as it conforms to your bodys shape. Our old ortho mattress did nothing of the sort.Sleeping on your side is more comfortable as your shoulders sink in rather than get in the way.Too soon to ive a definitive review and will keep old mattress just in case.Would consider separating to memory foam layer from sponge bottom and adding as a topper to old mattress if there is any problems.At the price I purchased at I can not complain. Its as cheap as a cheapo topper but feels soo much better.May pop back with more info if required\requested.So far worth the money as its cheap as a a very cheap mattress.

This king size mattress is easily as good as others at twice the price. I know this because our previous mattress came from a well known hand-made bed store and cost over £400. I managed to snag the Hypnia for £190 and I couldn't be happier. It's film, moulds well and the 12" depth is great too. Just a couple of things you need to be aware of; firstly virtually all memory foam mattresses (unless on top of a pocket sprung base) sleep pretty hot. You won't need a high tog duvet, secondly the thickness means that you'll need to get extra deep fitted sheets. John Lewis do them but you need make sure you've got the measurements right otherwise your fitted sheet will just ping off. Other than that the mattress arrives compressed and will need about 24 hours to reach it proper size. The two free memory foam pillows were a nice little bonus too.
