help me identify this please

[wilfy]

hi guys, i'm building a bubble tube for my boys and have got most of it finished.

i'm now looking at some soft padding to go round it kind of like a play mat you would find in a soft play area...

i want a material that is wipeable for obvious reasons. i've been in the local dunelm mill and while they had the foam i need i couldnt find any suitable material.

i've got some pictures from the sensory room we have been in today and this is basically the stuff i want



anyone have any ideas what it's called... the problem with not being able to touch it is i have a feeling i know what it is but dont want to order the wrong stuff
