Really happy with this mattress!! Read lots of reviews on here first as I suffer with back pain a lot and I have to say, one week in and I can definitely feel a difference.  It is very firm compared to my last foam mattress which I seemed to sink in to, but this is perfect for me and I’ve completely gotten used to it now and am sleeping very well. Already recommended it to a friend in work who has similar aches and pains as myself!
