Very comfortable mattress , we have both slept better since buying these ! My hip aches on occasions especially with my previous mattress when sleeping on my side , but since having this mattress it seems to take the pressure off of my hip . For the money they are very good value , my only reason for not giving 5 stars  is they are a bit on the short side length ways which is fine for us but someone 6ft or over may struggle . They also do seem to be cooler than a memory foam which we've had before and found uncomfortable . All said they are well worth the money , we've had some good nights sleep since buying them what more can I say !!?
