my tailbone feels better

Shawna from Olympia, WA– Verified Buyer

Great for an office job where you sit all day! just put a little air in the disc and you're good to go for all day sitting. I use to have issues with my tailbone hurting from sitting all day but this has helped that end. I highly recommend! A++++++++

Forces me to sit straight up

Kimberly from Fayetteville, NC– Verified Buyer

Takes a little time to get accustomed to this. Worked up to a full day after a week or so. Much easier than sitting on a stability ball and not so many weird looks at work. Wide enough to accommodate my wide hips. Better than other discs because I don't feel as though I am going to fall off.

Good product for sensory child

SLPmom from Land O Lakes, FL– Verified Buyer

This product is just what I was looking for at a fraction of the cost. It is being used as a sensory seat for my four year old son. It helps him maintain a seated position (while being able to still move a little). The only problem was that is has deflated already. I just reinflated it quickly and put the plug back in, but it is used at home and school daily. The funny thing is I have a three year old without sensory issues and he's wanting one as well. It's actually pretty comfy to use when seated!

Really like the weight of the disk

Christine from Washington– Verified Buyer

I am happy with my purchase of the seating disc by FitBall. The thing that I like the most about the disk is the weight of the disk.

got it for posture

debbe from Mississippi

I got the fitball disc to help my posture and help prevent lower back pain from sitting at my desk at work. It does help me sit up straight. I am still trying to figure out how much air I need as you really don't need much at all. I don't like the nubby things so I may try flipping it over and using the smooth side. It does help with the posture and pain and when I don't use it, later in the day my lower back will be tired and then I realize I forgot to use my disc. I try to use it everyday.

Good Product!

Barb from Connecticut

The Fit-Ball seat cushion eases the pressure on my arthritic hip while I ride in the car. I can inflate it to various levels depending on the situation. I recommend this product.
