After having a 'foam rubber' mattress for many years, we decided to purchase a more natural mattress. In this case, the mattress is made with bamboo materials. Unfortunately, our mistake was in not inspecting the 'low profile' on which the mattress rests. After requesting relief from the constant noises exhibited by the low profile pieces for four months--both from Mattress Gallery and the manufacturer--we removed both pieces this weekend. After receiving no assistance on the 'warranty,' we dismantled the low profile pieces only to learn the construction was piecemeal and the cheapest of materials. Many small pieces of cheap wood were stapled together to form the 'base' and covered with cardboard. Basically, all the small pieces were contriving to make noise any time someone moved. Lesson learned--Englander uses very cheap materials. We expect the mattress to collapse at any time now that we've seen the 'quality' of construction.
