I purchased this mattress because it was in the top 5 recommended by Which and I'm not disappointed.  Delivery was great, arrived on the date and time specified, packaged well and portable enough for me to carry upstairs and unwrap by myself. After a few days there is still a chemical smell but it's fading every day. The mattress seems comfortable but as it's for the guest room I cannot comment further. Which gave it a good comfort scoring so I'm confident guests will sleep well.
