I bought this as a one year birthday gift to the only man in my life that matters.. being my precious kitten. The price seemed reasonable, so I bought it. $129 for a piece of cat furniture measuring 45"H x 21"L x 21"W.
First off, this thing is HEAVY. For a 5'3 110lb girl anyway. I could barely lift the box to save my life and had to literally drag it to move it. Once the parts have been taken out of the box, assembling was less of hassle. The instructions were a bit hazy (just a picture with arrows), but it was easy to figure the assembly out just by looking at the picture.
The assembly itself is doable solo, but having another person to help is extremely helpful since some of the beams have to be held in place to be screwed in right. The beams also have to be screwed in extremely tight or else they'll feel rickety.
Overall, my cat loves this thing. The texture is perfect for scratching, so the furniture is fortunately saved from his paws. He's slept on the top tier for over a year now as well. I highly recommend this product, the happiness from your cat loving this thing will make you forget the assembly woes.
