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

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.

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.

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

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.
