I did my own customization on a memory foam mattress from Costco. Cut down the length, width, and depth with an electric carving knife.
Look up HMC mattress on Google.
We bought one from Handcrafted Mattress Company (HMC) several years ago and my bride still tells me how much she loves it. Not cheap but worth it to me, both for the Happy Bride AND my happy back.

Turns out that logo was from HMC. Elected to go with Portland Mattress makers and am VERY pleased with the result. They had my pattern on hand and the fit is perfect. Extremely comfortable as well. A huge improvement to the boat as we spend quite a few nights onboard..
