Following my twin bed mod I posted last year, I decided to undertake another mod that makes a 320 twin bed configuration even more convenient and spacious.
By replacing the bulky back cushions, that are really only necessary for sleeping in the queen bed configuration, with slimmer back cushions, seating becomes much roomier and, more significantly, the back cushions no longer need to be removed and stored somewhere, at night. Furthermore, we can also access storage under the side seats without removing the back cushions (the compartment lids are adapted with piano hinges, etc.).
To make the new back cushions I purchased OEM fabric from NuCamp (when you could still order directly from Elsie 😀). At the same time I also ordered a split seat back, which I installed as part of this overall convenience mod. The new back cushions are made from 2” thick high density foam and upholstery batting mounted on ¼” birch plywood. The fabric is secured with staples. Like the original cushions, velco strips hold the new cushioning in place.
As can be seen in the attached pics, I chose to make accessing raising/lowering the seat back(s) even more simple by creating small triangular corner cushions that are simple to remove.
This mod has worked out very well and fulfilled all my objectives. Seating is more spacious, yet there is adequate back cushioning. Cushions conveniently stay in place at bedtime and we find lowering/raising the seat back(s) much simpler, as is general access to storage behind the rear seat. Plus, everything looks as if it came from the factory this way. Obviously, the large cushions and large seat back have been stored away for easy conversion back to standard configuration, so a future owner may have the choice.
I will be happy to provide a few more details if other 320 owners are interested.
