Excellent quality! Following an extensive amount of research and having spoken at length with their customer care team (who were so patient and helpful), I decided to try a Button & Sprung mattress. I am VERY happy with the Drysdale - this is by far the best mattress that I have slept on. Having had a sleep trial with another company, I can honestly say that Button & Sprung is a much better mattress in comparison. I have been recommending it to all of my friends and family! Their knowledge and understanding of mattresses is excellent, they advised me to go with a softer mattress (as I weigh around 55kg), and so the Drysdale really is a perfect fit for me. I am really happy with it and will be replacing my other mattress with a Button & Sprung.
