If you try sleeping on the couch then you might want to try sleeping inside a comfortable Blanket instead of sheets especially, on cold nights.
Well, with the right blanket material you could make full bed sized blankets and seal three of the four sides to help keep the heat in and so your arms and legs don't come out and freeze.
You can also stuff this blanket, when folded over, into an actual sleeping bag for extra comfort and heat.
Cuddley, like sleeping on a plush Teddy Bear but, more comfortable.
It would make making your bed faster by including the two sides of the Blanket Bag instead of two different blankets to line up.

As far as I know, this already exists. In fact, you can also build it by tucking two sheets into the corner of your couch and climbing inbetween.
