I bought this Wunda Chair from Walmart (online) about 6 months ago. I am a Pilates teacher and wanted to be able to practice at home. I've ended up not using it because I usually just work out at the Pilates studio. This is a nice, sturdy, chair. It includes handles which assist with balance. The 1st 2 pictures with great lighting are pulled from the internet. The rest are ones I took of my chair.
Here is the exact model:

It sold at Walmart for $297 plus tax, but it looks like they don't have it in stock at this time.
I would also like to include a free 1 hour teaching session if you're interested!
