Artilife Closed Cell Neoprene Sponge Foam Rubber Sheet Roll, 1/2" T x 13" W x 60" L, Perfect Cosplay Padding, DIY Project Sheet - Easy Cut Non-Adhesive Multi-Function Soundproof Rubber Foam Sheet

I was looking for padding to put on my 2 post lift to protect the vehicle doors when getting in or out of the vehicle. I used half on each side and installed it with spray on contact adhesive. It is doing that job perfectly. it is soft enough not to mar the finish and dense enough to protect the doors.

I was looking for something more like sponge, or for cushioning, and this is unfortunately just a soft, very dense foam sheet on a roll. It isn’t as firm as cosplay foam, but it isn’t light enough to be used in construction of puppets or stuffed toys. It sort of sits in the middle where you just have a very soft and pliable material that is easily cut but still too heavy for most crafts, and too soft for the rest. If you are just looking for insulation or something to protect your stuff I am sure this is fantastic. It looked a lot lighter and like it had more give to it in the application photos but no. It’s soft, but very high density foam.

So I got this Artilife Closed Cell Sponge Foam Sheet Roll, mainly because I thought, “Hey, sponge foam sounds like a cozy mattress for my life’s problems.” But then I hit a snag: what the heck is “closed cell” anyway? Is it a secret society of sponge cells that don’t talk to outsiders? A foam version of a VIP club where only certain bubbles get to hang out? Or maybe it’s just foam that refuses to let water crash its party? Honestly, I have no idea, but it sounds important and science-y enough to justify my purchase. Anyway, this foam roll is surprisingly versatile. It’s dense, squishy, and somehow both firm and soft at the same time — like hugging a marshmallow made out of steel. I tried using it for all kinds of stuff: padding, insulation, cushion for my aching soul. It’s been a loyal companion through thick and thin (literally). If you want a foam that’s like a secret agent sponge — tough, water-resistant, and totally mysterious — this is it. Just don’t ask me to explain “closed cell.” I’m still googling that.

Little bit pricy

Seems like it will work nice. Thankfully, I’m not using it for cosplay or any location I’ll potentially have to smell it. It smells horrendous. I assume the smell will eventually fade. Smells a bit like a mix of cat urine, ammonia, and… vanilla? Very weird.
