It fits the 'Roma folding chaise lounge' very nicely. I did have to use a couple of bungee cords to fasten it to the chair, because the velcro straps wouldn't fit the chair in those spots.  I made the velcro straps into loops and just hooked the bungees through them at the head and foot of the chair.
That's why the 4-out-of-5 stars.
To make it VERY comfortable for me, I use a pillow from an older chair for under my neck, which has a long elastic strap to secure it.

Pros: Nice-looking and comfey!
Cons: Nothing, it's all good!
