We have 2 cat trees made by this company.  this is the first cat tree that I purchased followed by a larger version.  Both are fantastic.  Easy to put together, well made, designed well to encourage cats to use, and space conscious.  Even the larger version fits well in a smaller room and packs a lot of fun in for the cats.  Well balanced - my one cat(large ragdoll)can hang from the side and tree is very stable.  Love it!!!
