My 40 lb dog and I spent three weeks on this mattress. There were no problems with the weight and although I messed with the pressure level, the mattress never deflated. I got used to sleeping on it faster than I expected & it was a good solution for a short period.
Have bought many airbeds before and this one is light years better than anything I have ever tried. The lumbar support section makes it so you don't dip in the bed and have an achy back. You can actually get a good nights rest. Thank you!
