It's not the most solidly constructed, and it was a little hard to put together given that the base is two parts with two screw holes at the seam between the panels, but it's really cute and my cats love the lower flower bed (they have yet to jump into the top one of their own accord, but one cat will hang out and sleep there if I put her in it myself).  As noted elsewhere, the little compartment below the lower flower is not big enough to fit a grown cat inside (and trust me, my youngest cat tried really hard), which is a weird design flaw, but I use it to store small toys instead.
