Only you can decide.
Try them.

I hear what you say, and have done so in earlier years, but I'm not
convinced that lying on a bed in a shop, for a few minutes, is really

minutes, particularly on a shopping trip. I have found the same on
holiday - what initially seems fine can be less so, after a few nights.
