My wife and I have our regular TV/movie watching time from around 9-11 every night.
Recently I’ve been working through some games on my Steam Deck (Pokemon GRAND Colosseum, Baldur’s Gate 3, and Control.) and have just really found that using a regular pillow to support my arms is just hot and often blocks the vents. Same issue if I use blankets, plus I feel like these don’t offer enough support.
All this to says — do you use a lap desk? If so, are you married to a particular type or brand?
I’m probably looking for more of a lap desk than a TV tray type thing.
You mentioned seeing the mechanism pillow, they actually offer 3d print models for a lot of their connectors and mounts. There are several options for how you could use them, I’ve seen people do a long arm monitor mount that they can swing out over their bed and clip the deck to.
