2 Pcs Black Polyurethane Foam Sheet- 16 x 12 x 1.5 Inch Cuttable Foam Inserts for Cases- Packing Foams Pads for Toolbox Camera Storage and Crafts

When it arrived at my doorstep, I was very concerned because it was completely flat, less than an inch tall. Looking at reviews, somebody mentioned it was vacuum sealed. I cautiously cut the pack, then instantly air was pulled into it, and it started to inflate. Within a minute, it was fully inflated, a full 1.5 inches per piece as advertised. I use foam like this for shipping framed art. It is durable, firm, and works well. I think this 6 pack is reasonably priced for what I do, which is cutting this into pieces to secure my art in shipping boxes.

The polyurethane foam sheet arrives looking like it was accidentally mailed as a napkin, then proceeds to expand like it’s late for a science fair. You open the package, set it down, and suddenly you’re questioning whether you accidentally ordered “foam, expanding, theatrical.” It rises more than yeast bread left out for 24 hours and does it with the confidence of something that knows you weren’t ready. Five minutes later, you’re holding the full 1.5 inches and quietly wondering if you should’ve ordered two… or if you should line your kid’s bedroom walls with it and finally achieve household peace. For science projects—especially the “dad, we’re building a wind tunnel” kind—this foam is an unsung hero. It’s soft enough to forgive enthusiastic measuring, dense enough to hold fans and ducting steady, and compliant enough to kill vibration before it turns your dining table into a percussion instrument. Fans seat cleanly, airflow stays controlled, and the whole assembly stops trying to migrate across the table. It’s the difference between “experimental apparatus” and “science project that doesn’t embarrass anyone.” In actual use, the foam behaves like it’s been raised by engineers and parents simultaneously. It cuts easily, tolerates repeated adjustments, and absorbs noise and vibration like it’s personally offended by chaos. Every time you trim it, it forgives you. Every time the project changes direction (which it will), the foam just shrugs and adapts. And yes—at some point, you will pause, look at the leftover pieces, and seriously consider whether lining the kid’s walls might improve acoustics, concentration, and general household harmony. It’s not structural, it’s not fancy, and it doesn’t pretend to be anything it’s not. But for stabilizing, mounting, damping, and saving last-minute builds, this foam sheet is dad-tier problem solving at its finest. Quiet, effective, and way more useful than expected. Pros • Expands dramatically to full thickness (consistently entertaining) • Excellent vibration and noise damping • Easy to cut, shape, and revise repeatedly • Lightweight yet supportive for mounting components • Perfect for science projects, labs, and sanity preservation Cons • Arrives impossibly thin and mildly alarming • Compresses under heavier loads • Not structural—supportive, not load-bearing • May inspire questionable home-improvement ideas

I needed it for a pistol case, it was the right size. Worked fine. I trimmed it with an electric knife which makes a smooth cut,

It was big, im not sure if it was supposed to be easy to cut into but I needed it for a project and it was definitely hard to cut into. But again it is foam and worked good for my project

what I would call a medium density foam. I use it for padding under upholstery - custom oak consoles for 2nd row captains chairs in SUV's

Easy to cut and great quality. I use this foam for the internal structure of my needle felt projects and it does a great job. Doesn’t break down after thousands of stabbings with my needle.

Put this behind your headboard!

The sheets are vacuum packed, which is a good thing. One edge of two of the six sheets was not cut to the same thickness described in the advertisement.

Good product

I actually use this on my mattress I have a dip in my mattress and I bought these to fill that dip / Gap all I did was I took one piece and I cut it into the shape that I needed and it worked perfectly then I put those pieces underneath my mattress topper and I can't even tell that there ever was a dip and it is so comfortable, and I'm thinking about using the rest in my pillow that has foam in it as well

These are great, however they weren't exactly what we were looking for. Kept them anyway, never know when you'll need it.
