Ok this one took a bit of construction. My mom's friend had a quite insanely comfortable couch. When she had to move into a smaller house she offered it up to us and we jumped on it instantly. Put it in the basement and enjoyed it. My mom also got a memory foam pad for her bed but ended up not liking how it felt and tossed it down in the basement for storage.
So one day/night we had family over from out of town and my room got offered up as a guest room. I placed the memory foam pad on top of the couch, grabbed a bunch of oversized blankets my grandmother had knitted for me and my sister when we were kids and a sleeping bag.
It was honestly the most comfortable thing ever. The knitted blankets allowed just enough of the cold air in the basement through to keep me from getting too warm, the pad/couch combo was brilliant, and the entire place was dead silent. I plan on recreating that experience every night when I get my own place seeing as the foam pad is now mine and I plan on taking it with me, just need to find a comfy couch.
