Great for back pain
Excellent product for people who cannot sit on traditional chairs for extended periods of time. I have a proper saddle chair at home - this lightweight conversion seat means I can sit without fear of hurting my back when away.

Good alternative to a saddle stool
I bought this after a few failed attempts at other saddle stools. I love that I can just have this in my office and use it on and off throughout the day. It just sits on top the chair without attaching in any way, providing a bit of a balance-ball effect. It also comes with a hard base with a divot for using on really soft chairs. I have a mesh chair, so at first I used the seat on top of the base. However, this felt a little unstable to me, there were too many layers sliding around and it was hard to adjust. I currently just use it without the soft-chair base. It sinks in to the chair a bit more than it's supposed to, so there is a bit less active sitting and balancing, but this feels ok to me. Overall, I really like it. It's expensive for what it is, but I feel like it is a lot more durable than similarly priced saddle stools, and it's less of an all-day commitment! Plus I can take it home from the office and use it when teleworking.

It's a great device
My physical therapist as well as myself really liked this product as it's especially good for routines to address my physical issues and for what I need physically from hippotherapy. Also works well to use for Feldenkrais movements. . .

Give it a try.
I really think if you’re interested, you should give it a whirl. I liked the concept. The movement for my pelvis and lower back was great. I did not like the carpeted base and disc. (Pictures we’re attempted but I’m not sure they show the clarity I was hoping to get.) After about 9ish days of use it flattened out and made for a slippery ride. So slippery that, as I leaned forward a little, the round saddle base just slid right out of the base and plopped me on the floor. It was a good laugh for my students but I wasn’t amused. I would suggest the base and the extra disc that come along with the saddle should be backed in some type of rubbery/grippy material. Perhaps some kind of cross between a shelf liner and those things you use to open pickle jars. You could still get movement but without totally sliding out.

The Chemical smell was horrible and it caused an allergic reaction
Aside from being uncomfortable, the item reeked of a horrible odor. It caused irritation and an itching sensation from the other room. It goes back.

Awesome
Just what I needed! Due to hip, shoulder, and back issues, I need various options for seating or I get migraines and other pains. While I don't use the saddle all the time, it gives me all the variety I was searching for. It has quite a bit of movement, which helps keep pains at bay. It's light so I can easily bring this to work whenever I want. Pleased with this purchase.

this thing looks so stupid and I feel like a chump sitting on it but also.... I enjoy it a lot more than a regular chair. do I enjoy it in proportion to the price? not sure, but hey whatever gets me through the workday. I can pretend like I'm a jockey while answering emails haha

Awesome
I love this thing. I have tried so many ways to make office chairs more ergonomic, and it seems like I fix one issue but cause another. My back, neck, and shoulders feel better than they have in decades. Thank you!!!
