Completely pleased with this cat condo. Our 5-month old rescue kitten loves it! Has no trouble getting up to the top or back down. Stability was my greatest concern as our kitten is a crazy, wild curtain climber with advanced gymnastic skills. I wanted something tall but not too tall - this is the perfect height to satisfy her desire to be up high but I can still reach her. It's VERY sturdy, no shakiness at all. We have it on hardwood in the living room next to full-length corner windows with the tunnel piece 'window' facing outside and she loves curling up there. She naps in the tallest perch. Was a breeze to put together. Very attractive piece. Got the beige color, looks great with neutral decor, deeper tone than the white color pictured in the ad but it's a very light cool-toned beige (not tan) - clean and modern looking.
