2 Pcs Polyurethane Foam Sheet- 16 x 12 x 1.5 Inch Cuttable Foam Inserts for Cases- Packing Foam 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

Worked great for my needs

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

High quality foam

Put this behind your headboard!

A lot of restaurants have really hard seating and this is a great pad for those of us with basically no padding in the back. Just be careful about not leaving them behind. It's probably time for me to order another package.

Worked for my project, but expensive.
