At our appointed time went to DREAMS IN Derby and met a very pleasant and knowledgeable staff member, Joanne who after taking our sleeping profile showed us a number of beds for us to look at. Should just say, before were came we felt a little uneasy about our security re Covid. We needn't have been, everything was so clean and wherever we went someone was spraying behind us. We decided on the Therapur 3200 Mattress, Just firm enough but with the topping "pillow" of 4cm Gell foam, my wife and I agreed it was the most comfortable we had tried, so we ordered it. It came a week later on time, but in the middle of a cloudburst. The 2 delivery guys, without being asked to, did very well by putting shoe protectors on once inside our front door, and no problem. We have had the mattress now for 2 weeks and it's fabulous, just firm enough and the top is cool.
