(Just to clarify: I'm not sure why this is saying it's referring to the UNheated seat, as I did purchase the heated one... LOVE that is stays nice and warm for my senior kitty!)I am so thrilled to see how happy my cat is with this window seat!! She is laying in a sunny window, bathing herself and purring. :) She is almost 14 years old, and getting a bit arthritic, so I got her the heated seat, and she is in Kitty-Heaven! (The window is fairly close to the heat vent too, so she really stays extra cozy!)OK - First I have to comment on the packaging it was shipped in... Amazon shipped this in the original manufacturer's box, with only 2 little round sticky seals (placed by the manufacturer) holding the top end of the box closed... no shipping tape, no shipping box... nothing other than a label slapped on the retail packaging! I was truly shocked, as usually they are good about shipping things securely. And when I buy a $40 item (maybe not a lot to some folks, but it was a chunk for me) I really expect them to take some care when preparing for shipment. The box was damaged, and I was AMAZED that the hardware packet had not fallen out and gotten lost, because those 2 little round stickers were ripped and the box was over half-way OPEN when I got it! SO I almost took a star off for that, but that would be unfair to the manufacturer/product. It is not *their* fault that someone at Amazon was being lazy and didn't package this properly for safe shipping. (I hope someone from Amazon will read this and make sure it doesn't happen again... but I'm also going to fill out the "feedback on packaging" thing for this order, just to make sure!)Now that I got THAT out of the way, on to the seat: It comes with excellent, clear instructions, and is SUPER-easy to install. I'm a 50yo woman with arthritis issues of my own, and I was able to install the seat securely in the window with no help. It is hard to get the legs to snap/click into place - I had to push them REALLY hard to get them to click securely into place... but once they click (you'll know it - it's loud!) they are REALLY in there to stay! I feel totally confident that my cat is safe and won't fall (at least not due to any instability of the seat - it is very secure - installed with screws, not velcro).Here's a quick tip to keep in mind when you install the seat: Leave at least 1/8 inch between the edge of the seat and the window, so you'll have room to tuck the covering around it once installed. I had to un-do my first installation because I forgot to leave room to fit the cover around the edge that butts up against the window... now I have 3 extra drilled holes in my window-sill (but I'm not telling hubby about that just now... he may never need to know, since the window seat will probably be staying there forever! LOL!) Of course if we ever move, the seat is going with us, and I guess I'll have to fill in the holes then. ;) And on that subject... Personally, I would *NEVER* trust my cat's safety to those little strips of velcro. Our bedroom windows are almost 5 feet off the ground, and my girl is an old lady... I would be afraid she'd fall and get hurt with just the velcro holding the shelf. The holes you have to drill are quite small, and will be simple to fill in with a bit of wood-putty if you need to un-install the window at some point. I'd much rather have the peace of mind knowing my cat's perch is safe and secure than going the "easy way" just to avoid filling a few small holes. (Of course I understand some people rent and cannot drill holes in their window-sills... in that case, maybe I'd use the velcro, but also add some extra velcro beyond what is in the package, or some other way to add extra holding power... some kind of double-sided extra-strong sticky mounting tape, maybe? Or add another bracket underneath, that you can nail in?)As others have said, the unit itself (and the brackets) are plastic - sturdy/strong - and light-weight. Wood would make the shelf heavier than needed, so I don't have any problem with the plastic. I could see that clearly in the manufacturer's video, so it didn't bother me at all. The padding works well - along with the heating pad inserted inside, so that the surface doesn't feel lumpy or uncomfortable for kitty. (it might be a little more lumpy though, if you get the un-heated version). The faux lambskin cover has elastic all around for easy on-and-off to wash the cover, and slip it back on. My cat loves that stuff.Because my kitty is getting old, I put a tall dresser next to the window perch, so she can step down onto that, then jump onto the bed for getting down (our windows are quite high) and for getting back up again. She seems to be quite pleased with herself for getting up there. :)I totally love the product, and my kitty, Jasmine, thinks is PURR-fect! :)Oh one more thing - because I was having a hard time snapping the legs into place, I called the company to make sure I was doing it right, and they called me back within 20 minutes to answer my question - great service!

I bought one for every window for my cat. She loves them. Quite pricey but safe and stable and easy to fix. Recommended.

Está muy cómodo. La textura es muy suave y el producto es de buena calidad. Lo único es que no sirve el pegamento, se tiene que atornillar para que no se caiga.

Rabbits love it too no issues at all love the washable cover it has been in the wash twice so far.

Eccellente e stabile, molto carino, anche su un davanzale interno non molto profondo regge bene il peso di un gatto o due. Posseduto da mesi nessun problema. Ottimo in rapporto al prezzo.
