Replacement Mattress

[Jambalaya]

Has anyone had to replace a bunk house mattress? We are having difficulty finding one. We have an Outback 26KBRS. Need to replace a 28 x 84 bunk mattress. Any suggestions are appreciated!

Mine was a hack:
I bought a 4" bare foam gel topper for the main bed. Didn't much care for it and upgraded. I cut the topper to size and replaced both bunk mattresses. The corners compress with the mattress pad and fitted sheet, but no complaints from the kids.
