Hey there, I was going to make a thread but thought I had to check in with you first since you had a very similar chair
They had this one on sale for $89, so I tried it — it looks very similar to the one you recommended, the grey worked well, and most importantly it was returnable. I just received it yesterday, but the reviews are definitely right about it sliding shut on slick floors. :/Most mentioned tile, but I have wood floors, and you definitely have to be careful not to get trapped lol. It seemed pretty stable when I put a comforter under it, but that definitely hurts the portability which is one of the most important aspects for me.
Anyway, TL;DR: does your chair slide shut/collapse on slick floors tooisk( that just one of those things that you have to deal with with this style of chair? Any thoughts on something I could put on it to keep it from sliding? Carrying around a giant rug isn't really ideal.
