A surprising number of plastic/rubber components used in cheap electronics accessories will offgas. You notice an odd smell, that's literally petrochemicals entering your nostrils by the millions. Some of them can mimic biomolecules like hormones. I'm not saying they're necessarily all harmful but there needs to be a lot more research.
Ah, a better option for you I just thought of. Look into the DeckMate, it's an attachment that can be connected to different things, and comes with attachments to stick to other things.
For example, you can have a portable battery connected to your Deck. But also, a VESA compatible back that you can just screw into a regular Monitor Mount, and boom, Steam Deck stand with any angle you want at roughly any height you want.
Bonus, you have a lot of things you can mount the deck to!
