I like these for my walker so when I'm sitting on the couch or chair I rest my feet on the hammock so my feet are not on the ground and are elivated.
Easy to adjust, your feet are not on 2 seperate platforms it's one and seperated by the straps.
It comes in a black vinyl bag very tight fitting and foot hammock has to be folded just right to get it back into the bag.
I also comes with a eye mask that you can use to sleep at home and while traveling.
To me this is just as good as the straight across platforms. I like the straight across platforms better as it is easier to get my feet on.
