Just looking for a mattress for the bed, in my Buccaneer Elan 15 caravan.. Of course, it needs to be cut to a custom size. And ideally to fit on top of the existing cushions, so that my feet can dangle over the edge, instead of pushing up against the wooden end panel.
Decided to go with https://customsizebeds.co.uk/ – good testimonials, good price for memory foam. Includes stitched zipped washable cover, and delivery.
