## Customer Reviews

### ⭐⭐⭐⭐⭐ Love it so nice
*by Z***A on January 4, 2025*

Perfect for modern officeI will order more

### ⭐⭐⭐⭐ Nice place to pop a squat temporarily while at my standing desk
*by M***M on January 12, 2025*

This wobble stool was extremely easy to assemble and is well-made overall. The seat pad is comfortable, and I love how lightweight it is, making it easy to move around. It works great as a quick rest spot while standing at my desk, but it’s not ideal for my shorter legs. Other family members with longer legs find it more suitable—some think it’s comfortable, while others find it a bit awkward to use. One improvement would be a greater range for height adjustment to make it more versatile for different users. Also, because it’s a wobble stool, it lacks stability, so you need to be cautious not to lean back too far, as it could tip over. Additionally, the lever for adjusting the height is very stiff. I hope it gets easier over time. If you’re looking for this style of stool, it works well for its intended purpose, but it may not be the best fit for everyone.

### ⭐⭐ NOT adjustable
*by J***B on July 30, 2024*

Very easy to assemble, reasonably comfortable, great price, but IT'S NOT ADJUSTABLE. It has a handle under the seat that you can pull out, which presumably should release the piston and enable the stool to be raised or lowered, but it doesn't work!
