My husband LOVES this mattress, says it's the best thing we've bought in years, and his back pain has stopped almost overnight. I would like it to be a tiny bit softer as I like to sink into a mattress, but hope it will 'break in'. Gambling on a mattress online, has paid off, thank goodness - and I think due to reviews. Which is why I'm leaving this. 30-Jul-2015 Product: Retains more heat than I was expecting but very comfortable. 27-May-2015 Product: Excellent service and speed!! 28-Mar-2015 Product: Very comfortable and supportive 26-Mar-2015 Product: As above. It is quite a strong smell! 26-Mar-2015 Product: The mattress is really comfy, I'm very pleased with it. 23-Mar-2015 Product: Very comfortable and the extra 10cms compared to a king size comes in handy when the kids get in the bed! 23-Mar-2015 Product: I'm unhappy with this product it's supposed to be covered in a temp regulating cover my wife and I find it very warm to sleep on 23-Mar-2015 Product: great product - could use advice on what base it needs to live on - i.e. can it be a slatted base or does it need to be a substrate without any gaps?
