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.

Comfortable, Stylish, and Great for Casual Seating
The OLIXIS Criss Cross Legged Chair is a really nice option if you prefer sitting cross-legged or want a wider, more relaxed seating style compared to a traditional office chair. The armless design and wide seat make it easy to shift positions throughout the day without feeling restricted. Comfort-wise, the padding is decent and supportive for short to moderate sitting sessions. The adjustable height and swivel function work smoothly, and it’s easy to find a comfortable position whether you’re working at a desk, doing makeup, or just using it casually in a bedroom or home office setup. The minimalist look is also a plus—it blends well with modern decor and doesn’t take up as much visual space as bulky office chairs. Assembly was fairly straightforward and didn’t take long. One thing to note is that since it has no wheels, it’s not ideal if you need to move around your workspace frequently. Also, while it’s comfortable, it may not be the best choice for long, full workdays compared to a high-back ergonomic chair with more lumbar support. Overall, this is a stylish and functional chair that works great for light office use, studying, or casual seating—especially if you like the criss-cross sitting position.

Absolutely LOVEEE
I loooove this chair. I work from home and it is so comfortable to sit in any position. It is great for sitting criss cross but you can also sit normal or on your knees. Very stable and easy to put together. Great quality
