We decided to replace the mattresses in our Excella rear bath. As they are rectangular we went to a local mattress store that does custom sizes. Reasonably priced, but they could only guarantee the width dimensions to plus or minus 1.5 inches.
So we ordered two mattresses from mattressinsider.com. Correct size, 34x75. Free shipping. Ordered on a Friday, and they arrived here the following Wednesday, FedEx.
Very comfy and seem to be well made. Cool gel. Recommend the company.
