I bought this with the intent of using it as a sort of "fitness ball" that's not actually a fitness ball if that makes any sense. I work a desk job constantly and its nice that I can just plop this thing into my chair to alleviate my back problems. When I asked my chiropractor about it and eventually showed it to him, he said it would "help me keep pressure off of my sacrum" which is the lower back area. And it does indeed do that from what I've seen and has also been helping with my left leg siatica problems.

The cushion has 2 sides. One spiky and one not so spiky. I tend to prefer the not so spiky side but I didn't find the spiky side uncomfortable. So if you need it for that feature then I'd say its at least comfortable. I'm not sure I need it though...

Bear in mind though that the extended use of the product does wear me out... About every 1-2 hours or so I have to take a break. However, when I told my chiropractor this he told me that that's a good thing. So basically if I get tired it just means its time to take a break by either going for a walk or taking the cushion off of the chair.

I'm gonna say this product is well worth it if you suffer lower back problems like me.

This is the second order of this disc. I need it to improve balance after a serious fall down a flight of stairs. The first disc wouldn't inflate much but the second one inflected with the first try.
The company was most helpful with me and sent another pump for the disc but that wouldn't fit the opening so I ended up buy another disc since I never did find where we put it after inflating the first time. The first pump wouldn't hold the air in but the company gave me a very helpful hint on how to do it easily and it worked perfectly the first time on the second disc.

I am an administrator in an elementary school setting. We are always looking for new ideas to help kids that have problems sitting still in the classroom. Some kids simply can't sit in a seat for long periods of time and have to be able to move. It is so much easier to allow kids a form of movement in their chairs versus providing punishment for, "refuses to remain seated." These cushions are very effective for my school and many of our students. Yes, all of the students will want to try them out at one point or another, but honestly students that do not have issues with staying seated, lose interest very fast. On the other side, students that need to move never tire of these cushions.

These cushions are made of a very thick rubbery material. They are not going to burst very easily and they do not take much inflation to get to proper fill. On one side of the cushion there are small nubs about a mm in length. On the other side, there are longer nubs that resemble the industrial rubber floor mats that you wipe your feet on. It was very nice that they included a hand pump and a needle with each cushion.

I did not receive any type of discount, compensation, or products for writing this honest review. I think this product performs very well and want to pass the information along to others. Hopefully, other people will discover an effective way to help some students that truly need products like this to make it through a long seated day at school.

The cushion itself is great. I got it for two reasons - helping my balance for golf and also to help my posture while I sit to do my crafting. It's great for both these purposes. However, I only gave 4 stars because one of the selling points is that it comes with a pump - very beneficial! I followed the instructions to use it at an angle so that the needle would not puncture the rubber on the other side, and it ended up breaking the needle. First time I used it, and the pump is no longer effective --- or I have to now search for a new needle that fits into the pump. This was very disappointing. Why couldn't they just provide a shorter needle for the pump?
Additional comments -
I have been working extra long hours and brought my balance disc in to work to sit on. I find it is great. It makes me sit up straight and keeps me upright instead of slouching. Additionally, it has little bumps along the surface that keep the blood flowing!!!

For years I've had lower back pain that comes and goes. I exercise regularly and am a normal weight for my height, but working in a profession that requires me to sit at a desk all day definitely makes it worse.

I purchased a back roll/support for my chair that was recommended by my physical therapist and, instead of helping with my symptoms, I found it uncomfortable and annoying. Moving on I debated whether to get a balance ball chair or just the wobble cushion to put on my current office chair. Based on the price alone I started with the wobble cushion and I can't believe how much I love it!

At first I found it hard to get used to and used it only a couple hours a day - it was more the texture on the cushion that bothered me than the stability. After a week or two I naturally got used to it and now sit on it all day every day. What prompted me to write this review is that I brought my kids to work with me last week and they took turns sitting on my cushion. I thought I was neutral about the cushion's benefits, but once I didn't have it for a day, my chair felt really uncomfortable and I could feel my back. Great product!
