Foam rubber blocks

[Let'sgoflying!]

I need a chunk of ‘hard’ foam rubber, ~ 16” x 4” x 2” to jamb between two seats so’s stuff won’t fall between them.
It has to be something I can cut to fit the shape; knife/hotwire etc
Where to get that?

Make a cardboard mold and “ Great Stuff” ?

Where to get that?

Fabric stores and craft stores usually have a good selection of foam types with fabric stores better if you have one close.

Pool noodle?

Maybe old lifejacket or pool noodle/pool float cut to size and get someone to sew a cover for it. Roll up a towel? Stadium seat cushion? Maybe cheaper than trying to buy raw material

That’s what reminded me!
I need to measure mine.

Electronic equipment, audio and video, is often shipped in closed-cell foam--this is the firm stuff. They get a lot of it. In the past I've gotten it for free.

I've used them for gun/optics case foam. Good firm to deal with.
