The 5-post top perch is very spacious

We had one of those cheap trees before that would rock every time the cat moved. This one has five posts supporting the top observation perch, so it feels rock solid. The light grey cushion is actually padded well and I love that I can just throw it in the wash. My cats are 12 and 14 lbs and they fit together on the top 65x45cm area without hanging off the edges. The single ramp from the ground is great for my older boy who has stiff hips.
