I had this mattress (57" x 90") made for my camper at McGeachie's Foam shop in Langford only to find out that my campers is now to small for our growing family. I have sold the camper but kept the mattress thinking that it would fit into the new trailer that we bought. Much to my surprise a camper mattress is way longer than a trailer mattress. The mattress was made in Feb, we sold the camper in April and bought out new trailer. We only slept on the mattress once. My loss could be your gain.
Any questions please let me know.
