Delivered to room as directed, not unpacked and placed on bed by delivery men in case there was a fault, how do you know if there is a problem until it's unpacked? The mattress itself was a replacement for a well known bed retailers mattress which sagged within 6 weeks. So to get to this mattress, firm enough to give good support, deep sides, sleeping better than I was but have decided after several new beds and mattresses over a period of about 6 years, that my body is the issue not the bed. Would I buy this again, yes I would. Is it comfortable, yes it is. Only time will tell.
