excellent quality, Good Support
I got this on sale for $67. The process to assemble it was very straightforward and used an Allen wrench. It was rated as the best item in its category and had five stars. I wouldn't consider it a gaming chair, Although it tries to be one. It feels more like an office chair that was glam up to be a gaming chair. But it does an excellent job at supporting a tall large individual, Excellent Support, Good posture. Worth every penny, But not in the same category as a typical gaming chair. Lack some of the bells and whistles had a typical gaming chair would have, But every bit the money I paid for it. If you want something nicer then you need to buy like a $200+ Gaming chair with the bells and whistles.

I LOVE MY Criss Cross Applesauce Office Desk Chair IS THE BEST
Color: Cream, Size: PU Leather(No Wheels)
The Criss Cross Applesauce Office Desk Chair is a unique and innovative addition to any workspace, offering a blend of comfort, functionality, and modern design.
What immediately stands out about this chair is its ergonomic design. The criss-cross frame provides excellent support to the back and promotes proper posture during long hours of sitting. This feature is particularly beneficial for reducing strain on the lower back and promoting overall spinal health, which is essential for those who spend extended periods at their desks.
The chair is upholstered with high-quality materials that offer both durability and comfort. The cushioned seat and backrest provide ample support while maintaining a plush feel, ensuring comfort throughout the workday.
Another notable feature is the adjustable height mechanism, which allows users to customize the chair to their preferred seating position. This versatility ensures that the chair can accommodate individuals of varying heights and preferences, enhancing overall ergonomic comfort.
In terms of aesthetics, the Criss Cross Applesauce chair boasts a modern and sleek design that complements contemporary office decor. Its minimalist appearance blends seamlessly into any workspace environment, adding a touch of style without compromising functionality.
Assembly of the chair is straightforward, with clear instructions provided for easy setup. The sturdy construction and stable base ensure reliability and safety, providing peace of mind for users.
While the chair excels in comfort and design, some users may find the criss-cross frame design to be unconventional compared to traditional office chairs. It's important to consider personal preferences and ergonomic needs when choosing a chair that best suits individual comfort requirements.
Overall, the Criss Cross Applesauce Office Desk Chair combines ergonomic support with modern aesthetics, making it a practical and stylish choice for enhancing comfort and productivity in the workplace. Its blend of functionality, comfort, and contemporary design earns it a recommendation for anyone looking to upgrade their office seating experience.

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.
