My test dogs are more likely to medium to large, so far as they are not quite the right audience. However, they love both to rest on an elevated post. And so that's not always the chair, we wanted to try out this part. The structure is quite simple, however, was missing a screw (which was easy to replace), or there was too short a screw in. Built this "bunk bed" very stable and can actually wear also medium and large dogs - now you just have to go up - and plan to stay. 1 candidate to be shaken by anything, has it not gafackelt long. Candidate 2 (at issue actually), only looked something evil, then lay down on it but good.
A kind wieauchimmer cooling effect we can not find (yet). Luftzirkkulation under belly could also be a good thing in hopefully next summer.
