While we've been happy with the comfort of the bed in our 2021 T@b 400 I found on our last long trip I was slightly less comfortable than in the past. As a side sleeper who's 6'2" and 195lbs we added a 2" memory foam topper and covered that with a fitted pillow topper to make it more comfortable for me. The two additions seem to be wearing out a bit causing the slight discomfort. A few years ago we purchased from REI an Exped MegaMat Duo in the long double wide size to use when camping in the back of our truck and for guests to sleep on the floor. We find it extremely comfortable. Today I decided to see how it would do in the 400. I pulled off the old memory foam and pillow topper and laid the mattress directly on top of the factory mattress which is still on the froli system. I fits remarkably well, even with the angled corner, with the dimensions being 76.6"x52"x3.9". And it is extremely comfortable on top of the factory mattress. I also like that I can easily pull it out and still use it for truck camping or in the house and I don't have to remove the factory mattress and store it anywhere. I also like the adjustability of it by adding or removing air to change the firmness of. Anyway I know some people have been looking for replacements or changes to the bed to make if more comfortable so I thought I'd throw this idea out there. They are not cheap but no good mattress is and with the versatility of this one I think it makes it a bit more easy to swallow. Plus it's an easy return at REI if you don't like it. So far I'm happy with it. We'll be camping for 4 nights this week so I'll let you know if I feel differently after that.
