Hi Kodie,
They hold quite a bit of air - which isn`t necessarily a bad thing - but my guys don`t like the wobly idea when the first stand on it. Maybe less of a problem with newfies because of their weight.
I found that once the air is released the bed becomes hard.
Further, my friend borrowed it for her 2 old boxers when they went to kennels. When it came back it stank to high heaven and even after scrubbing it with alsorts the smell is still there!
All in all, it just lies here looking pretty.
Bought several Kudos beds - same easy clean idea - and my dogs love them.
Maybe it`s just my guys being difficult.
