Something like this.
Go on amazon and type “zero gravity knee pillow”. This is the kind of one I have https://www.amazon.com/Hermell-Elevating-Post-Surgery-Sciatica-Removable/dp/B0024GX6G8/ref=mp_s_a_1_3?dchild=1&keywords=knee+pillow+zero+gravity&qid=1588302844&sr=8-3
I think this one is better but it seems expensive: https://www.amazon.com/Angle-Back-Support-Systems-Immediately/dp/B00F98BITA/ref=mp_s_a_1_1_sspa?dchild=1&keywords=knee+pillow+zero+gravity&qid=1588302844&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzTFUwMFhZU1czVTRRJmVuY3J5cHRlZElkPUEwNTkzNDg1M0VVRDY2NDI3S083SiZlbmNyeXB0ZWRBZElkPUEwMjA0NjMxT01OVDBFU0EwTkomd2lkZ2V0TmFtZT1zcF9waG9uZV9zZWFyY2hfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
