I think the bed system could be somewhat improved. The vanilla beds are fine to stay as they are, but a better alternative could be implemented.
The Structure
The feather bed would be a multi-block structure, requiring some new interesting blocks. The structure would consist of,
- Six Mattress blocks (made with wool and springs)
- Four Cloth Sheets (made with wool) (a tenth of a block tall)
- Two Pillows (made with feathers and wool) (half a block tall)
These would be arranged like you'd image (mattress on the bottom, then sheets and pillows on top)
The Functionality
Why all that effort? Well, unlike normal beds you'd be able to nap in the day, and skip the whole day. However if you take a nap, you can't sleep at night. You'd also be able to sleep for small periods of time, not just a whole night/day.
The Nerf
Crops would not grow whilst sleeping in a featherbed, however food would be cooked and ores smelted etc.
