I have a living room PC - a mini pc plugged into my TV that I control with a Bluetooth keyboard and mouse or game controller. It’s so comfortable just sitting back into a sofa to game. You could also get a laptop stand/lap tray for the keyboard for more comfortable typing on your lap.
Basically it doesn’t need to be either a desk or a handheld. You can have a halfway of a PC on your TV. I also dock my steam deck and play on my TV, which you could also use for IF if you have one.
