We had returned an impulse buy from Groupon as it was so uncomfortable. We then went to Hafren's and were so amazed by the choice. We spent a lot of time trying out different beds in our price range and eventually went for this Thetford silk 800. After the previous disaster we were rather apprehensive but had a great nights sleep which has continued every night. This is a wonderful mattress of very good quality that I would recommend to anyone.
