I've had the mattress around a month now and very pleased with it. It is very comfortable and good value for money. Even though this mattress isnt as deep as other mattresses it provides a firm comfortable nights sleep even on a dilated base. I have a disc and joint problem and rheumatoid and osteoporosis arthritis and was having difficulty sleeping and getting comfortable during the night. Since getting this mattress I've had a much better nights sleep and wake up with less pain and stiffness. The only drawback that stops me giving it 5 stars is that it seems a bit small for my double bed base and moves about on it and slips down from the headboard about 2 to 3 inches during the night.
