If had you active cat or multiple cats this would fall over easily. It will not stand up to much heavy use. For a senior cat with tree in corner and not used daily it works.

My 2 male cats (brothers) who are about 12-13 lbs. each jumped on it at once.  I've seen them both on it ant the same time and they love it.  Also it looks good against the wall of my home office.  It's very sturdy and I expect to have it a long time.

If your cats are very large, the platforms and cave doors may be too small, and it's not as sturdy as I would have hoped.  But I have 7 cats who all go flying all over it at once.  All in all, the cats absolutely love it.

Cats love it. The platform is not entirely flat though, so it wobbles a little but cats are light enough that it doesn't seem to be an issue. Also would not work well on an uneven floor, luckily I don't have one but I know plenty of older houses do.

My husband and I agree that this is not a very stable piece.  Our kitten will have nothing to do with it.

The cats love it, but I can't get it to lean without falling under their weight - so it scares me  - so instead of having it leaning, I just have it vertical in a corner so they can stretch up but don't climb it.

My cats adore this thing.  I does wobble a bit when they go tearing up it, but they are small cats and it can handle their weight.  Not sure it would work as well for large cats.
It was tricky putting it together by myself - difficult to hold the pieces together and bolt them.  I covered the bottom with felt so it didn't scratch the floor when opening the door.

For $40 it's not bad.  It went together in under 10 minutes.  Sisal wrapped posts have been used for scratching. The biggest issue is platform size.  This may be great for kittens or smaller cats, but my 12-pound cats have trouble traversing this tower.  There's not a lot of space to stand on level 2 that isn't underneath the top layer. That lack of space makes it harder to get their footing to hop up. Our more active cat now tries to jump straight for the top, which causes some wobbling. Top bucket barely holds our medium-sized kitties when they curl. `We put it in front of a window, so it's fine to perch and watch the birds. If one were to try napping, I'm sure they'd fall off during the first stretch.

I have bought 3 of these but these break pretty easily if your cat is aggressive with them.

UPDATED TO TWO STARS: I've had this for less than a day and it has already fallen over three times! I have two 8months old kittens, the bigger one weighs less than 9lb and yet it falls over when he jumps to the top. He didn't get hurt, but I'm afraid it's not safe to leave anywhere without some support in case it falls. I don't think this is a good buy, but my cats seem to like it so I'm keeping it.
I love the size of this cat tree. It's tall and has lots of space for bigger cats. I found the carpet to be very cheap and not a pleasant color, I was expecting more of a neutral color. I bought the brown version. It comes completely assembled, except for the top part which come with 3 screws partially in already. The wood on the post had a crack on mine, so I had to shift the way the top went a couple of times until I got it right and secure. It wasn't super easy for me to screw the top in, so I needed a chair to make me higher and put a good amount of strength to get all 3 of the screws in properly. If you're not short as I am, it's probably going to be much easier. Overall, I think it's good for the price. Just make sure to check for loose staples before you let your pets on it. I've found a couple. Also the carpet comes off very easily, so I don't think this will hold very well with time, but it's not too bad. I'm giving 4 stars because it's pretty decent for 70 dollars.

Not the sturdiest, good enough though mind you, cats love it

I was worried about the stability of it as three of my cats are close to 20 pounds. The cats like it and it has staid put.  When the cats approve, who am I to argue

Great for one cat it is a bit wobbly so i would be afraid of it falling if two cats were jumping around on it. But it is great and looks like the picture (color, design,etc)

The cats love this but not as much as our old one which was much sturdier.  The perches are kind of small for our cats and the carpet/fabric came unglued inside one of the "houses" after 2 days.  The dangling mice didn't last long but that was to be expected.  It is quite wobbly and unsteady but will not fall over.  Overall it is cheaply constructed but seems to be holding up ok so far.

The tree is a bit unstable like other reviews said, but it's not enough to fall over even if the cat is pouncing on it. Unfortunately it's only useful to the platform above the first cubby, because the area with the big cat cubby is straight above the small cat cubby, it makes it difficult to get up and down from that point. My cat can't use the three tall platforms and the toys because she can't jump high enough from the ground to the bit platform.

Base is pretty heavy- my little beast of a cat has only tipped it over once, and not for lack of trying.

A bit wobbly, my cat does not use it often and I think i need to lower it since he probably doesnt trust it.
