hey its ergotron lx sit stand, bought it here: https://www.newegg.com/p/0RC-000K-00034?Description=lx%20sit%20stand&cm_re=lx_sit%20stand-_-9SIA25V23B3974-_-Product
its def one of the most expensive monitor stands u can buy and i bought it originally for other purposes and found it had this good use case as well. its good in that it has a very long arm and can go very low but know besides being expensive its also heavy so not something u wanna take on and off a desk often.
I use for my bed a different common cheapo light stand that does the job also well. since it has a shorter arm tho i needed to clamp it onto an overbed table so can get it in a good position.
(if ur bed is very low like on the floor btw this setup will likely not work for u)
overbed tables u can buy an amazon as well. my overbed table and stand(H-100 North Bayou) i bought locally and dont se them on amazon but they have tons of very simliar items that should be just as good. for the stand u want something that will go low, so prefeably with a straight bottom arm, myb something like this would be good: https://www.amazon.com/HUANUO-Single-Monitor-Stand-Adjustable/dp/B08FB7WFCT/ref=sr_1_14?crid=KTXJIF4J8YV8&keywords=H-100+North+Bayou&qid=1669564935&sprefix=h-100+north+bayou%2Caps%2C208&sr=8-14
i use some ergotron vesa mount that came with the other stand to connect to the keon mount with zip ties, but other vesa plate thingy probably work well or maybe just try tying it to the arms plate. sucks that keon didnt design it with vesa compatability so had to do this scuffed zip tie hack, but once all set up and done, get completely hands free best amazing experience possible with the keon, have fun 🙂
