Perfect little black chair
I bought this chair for four reasons:
1. My favorite color is black, but the company offers different color options.
2. The height of the chair was exactly what I was looking for. I did not want a tall back for the chair. The chair is close to the ground, which is a plus for me, my back, and my knees as I get older.
3. The chair comes with the option of wheels or no wheels; I chose the no wheels option, as I get dizzy and sick when I spin around for too long.
4. The chair’s wide back and seat design are perfect for me, since I prefer to sit criss-cross in a chair.
Pluses: It reclines, is comfy, and can be cleaned and moved easily.

Great chair, highly recommend!
Color: Cream, Size: PU Leather(No Wheels), Color: Cream, Size: PU Leather(No Wheels)
Very nice looking chair! It is comfortable, classy, and durable unless you have a cat like mine who used it for his claws. It was easy to put together. All of the hardware was of good quality and everything fit perfectly. My 14 year old daughter even put it together herself. We actually bought two of these. The other one is in my daughter‘s room for her vanity. I highly recommend them whether you’re buying it to sit crisscross or just for roomy comfort. It is a very comfortable chair and looks elegant.

New Favorite Desk Chair
This chair is exactly what I was looking for! It is simple to put together, very sturdy and very comfortable. I typically tend to sit criss cross while at my desk and I can do that very comfortably with it. Im a bigger girlie so a chair that can hold weight or deal with me shifting positions was very important to me.

Comfortable chair
Color: Cream, Size: PU Leather(No Wheels)
Ordered this chair for my daughter for Christmas. It's a great chair. It's very comfortable. She wishes it had wheels. I didn't see a way to add wheels to this base, either. Still a good chair. You have to make sure where you put it you can spin to get out of it. Pushing it back and forth on carpet doesn't work well.

Great Office Chair
I purchased this chair to replace the old one in my son's room. I really like the look and style of this chair. It was easy for me to assemble and the riser functions really good and the stability of the base is very good. I like the wide design as it has more back support and seat support.
