It is likely you mattress was manufactured by Handcraft Mattress Company (HMC). If so there is a tag on your mattress with a number o. It that identifies your exact mattress template. I order an all cotton mattress pad with a water proof liner and Egyptian cotton top of the line linens They were pricey at $800 for the set. I am very happy with the quality and fit.
