Permanent Sleeping Bag

An example of a bed involving a balance between the blanket and the mattress and few distractions or complications. 

The other day I was thinking about this issue in life which is that I really like beds that are just 2 parts. A mattress or futon and a heavy blanket. This is how I like to sleep 100% of the time and it is a form factor that I think looks quite neat of done in the right way.

So I was sitting considering life and blankets when it dawned on me that one of the reasons I really like this schema is because it is so easy to clean and aesthetically balanced, however one problem with it is that it is hard for tall people like me to not end up with cold feet. So I suddenly realised the perfect (not really) solution. Have a single roll up blanket at the end of the bed. This way my feet would be locked in and not get cold (this is really a big problem for people like me) and it would be sort of a self cleaning bed. A friend of mine also brought up that it could be used as a padded seat when rolled up but I am not sure if that something I am eager to take advantage of. I was also considering making it with the roll under the end of the bed but Zen told me no.
