TREKOLOGY YIZI-LITE Anti-Sinking Sand Cover & Ground Sheet for Camping Chairs, Fit YIZILITE Camping Backpacking Chairs

YES, it fits REI Flexlite chairs. It wraps up with the chair fabric and fits in the bag just fine too. We have only used them once, so can not say how they will last. However they are sturdier looking than anticipated, with thick rubbery “feet” at the corners. Seems good.

Used this for 6 days on the Salmon River in some pretty deep sand and it didn't just do the job, it excelled! Like others I bought it to use with my REI Flexlite Chair and it fit perfectly. Last year I didn't have this when we did the same trip and I spent 6 days sinking, tipping, and generally just struggling with my chair in the sand. This year no sinking, tipping, or struggling! I can't wait to use it at the beach later this year. Also, after those 6 days of pretty hard use I didn't find any bad seams, or damage to the product itself. Very happy with this purchase.

Bought this for REI flex light air and used 4 nights at pictured rocks on the sandy beaches there. I am large and heavy and think I have come to the conclusion that the ultralight chairs just dont work well for me I think I will try something larger for comfort, but this attachment did support even my large 225 pound weight on the sand without just burying the legs in. It was easy to attach and remove and stow and it functioned exactly as it should. It is a little on the heavy side if you are counting grams but if you know you are going to be near sand and have ever tried one of these chairs without one of these, then you know you probably need this, and this one does indeed to what it is supposed to.

Bought to use with the REI Flexlite Air chair which does not have its own base. Fits nearly perfectly by length and it is just tiny bit too large by width, causing the material to be just a bit loose but is still completely usable. I will most likely just stitch it to be about half an inch less wide and it will go from good to perfect. Recommend this for those looking for a sand sheet like this for the Flexlite Air.

Fit pretty well in my REI Flexlite Air, but the bolt broke after used ~5 times. It’s still functional as you only need to bolt to tuck it, but still kinda annoying.

Works Great on the REI Flexlite Air!

My little trekology chair would sink in the sand. I tried putting a towel under it, but it would just sink into the towel. This little gadget did the trick.

I was really cheesed off at REI for not making a beach mat for the REI Flexlite. Searching on Amazon, it didn't look like any competitor's ground mat was the proper dimensions. Then I found this baby. Ordered one as a test, assembled my REI Flexlite chair and crossed my fingers. It fit great. No excess slack, tight fit, but not too tight. It's like it was designed for this chair, and it was cheaper than a lot of the other ground mats, too. Fits right in the chair's stuff sack. Couldn't be happier. I immediately ordered a second one for my other Flexlite chair.

It’s light and works just as it should. What’s not to like?
