I bought Queen - 3 inch Natural Latex Medium Soft Mattress Pad and Queen 3 inch 100% Natural Ultimate Sleep Latex Mattress Pad, FIRM Density and put them in Allersoft Mattress Pad made of 100% cotton, dust mite and allergy protection, 9" Queen for custom mattress. This was in 2013. It has worked very well for this purpose and has stood the test of time. Note that I do not recommend latex rubber pads as they smell awful, but a mattress topper is perfect for the Job!
