My wife and I find the foam mattresses in our 542 a little 'hard' on, well various bits after a few nights even though I've tried toppers. So whilst I was the recent show @ the NEC I popped over to the Duvalay stand and asked what bespoke mattresses would cost. Well, they pointed at some sort of lightwieght recycled plastic bottle foam and I also looked at sprung type. I know that the sprung are about 10kg heavier but in the end they are so much more comfortable so I opted for the sprung, they do cost £400 inc a £100 show discount but well we're away for about 7 weeks in May/June so hopefully it'll be worth it. Had to submit detailed drawings of them for manufacture but expect delivery in 3 weeks.
Also had new higher backrests to front dinette made locally at a furniture upholsters, ummm, comfy.
Am I wus or wot, here's hoping.
