We have a fixed full width rock and roll bed from Titan Beds. This is a 3 seater and comes in 1300mm and 1400mm widths. Also available as a 2 seater.
They also make one on sliding rails, but only a 2 seater in 1120mm and 1200mm widths.![]()

Titan Beds Vari-mount Seat/Bed | M1 Tested | ISOFIX Option
Titan Vari-mount, the ultimate versatile Seat/Bed solution for camper conversion. Mounted on a rail system the seat can be multi-postioned along the rails to meet your needs.www.titanbeds.co.uk
I found them to be really helpful.
They may have something that meets your needs.

What did you end up with in the end?Really like the smartbed but they don’t do a crash tested full width and the raised rail system ain’t as practical as the flush rails. Going to have a look at fabworx
Where did you have the glide motion fitted? I’m looking at a similar set, love the versatility of the rib bed. Does it move freely on the rails and secure when locked well? CheersRIB 150cm on Glidemotion rails. Was bloody expensive but the wife wanted the best so she paid!! 7 positions to lock it. And comfy as anything. Sits quite high though on the rails but as it's mainly for us when we are away our 6'1" son has no issues. Apart from his head is on the roof sitting in the outside seats but he is short of leg and long of back.
