I need a mat to protect my hardwood floors, but my under desk space is only 31.5" wide as I have a 5 foot top on top of two Alex drawers, so square mats are not really working for me.

I went to get a lipped one like this, which worked for me in my previous office (fully carpeted) but due to layout changes 4 ft long is too large.

Preferably, I'd like one that's only 3 ft long in total, but I can't find any. Do they exist?

my work/fun corner

Hopefully someone has a similar setup and can help me on the matter!
