Measuring 79 x 54”, it’s the perfect length for the 80” bed (once you put on the fitted sheet) and it’s approximately 4” inches too wide, which is easily trimmed to size with either scissors or an electric knife.

Every mattress pad is custom made for no extra charge, including for the curved shape of the J bed. The inventor and business owner was a vendor at Quartzsite and I highly recommend their product!
