I have this Coleman set up for my bed. It’s a cot & mattress (so if your mattress leaks air, you still have support and can get out of bed a little easier): https://www.amazon.com/Coleman-Camping-Mattress-Folding-Battery/dp/B00AU6AVLW/

I also have this Intex inflatable corner couch for chilling in. *The price usually dips to $80… it looks like it’s $114 currently: https://www.amazon.com/Intex-Inflatable-Corner-Sectional-Cupholders/dp/B079Z2QWYQ/
