Foam worked well. Easy to glue (3M Super 77 spray adhesive) and easy to bend and staple around the rail. It feels a little "squishy" when you have it just sitting there and push your finger into it, but once it's in place and wrapped with the vinyl it's perfect.
Needed this to make an 8'x4' padded railing, gave just enough overlap so I could cut a tiny bit off and then properly fold it over the edges. Cut nicely with a pair of scissors too. Was packaged folded up but there were no real noticeable creases, especially after laying it on the railing. A bit expensive but was a good high quality foam that fit my needs exactly.
Great material and great price.
great help from the customer service reps!
Bought this for building an 8ft table. Perfect to work with - light, with good padding, but also easy to cut as required. Highly recommend.
