To make it easier to sit up and work/play in bed, with decent neck support I built this.
A wedge pillow is hot, weighty and awkward- so on bad days, the effort of picking it up and moving it around could be too much, and also I am pretty heat intolerant so wanted something that could breathe more.
I have made about six different version of this, including ones that don’t automatically rise.
I have also been hit on the head by those, because then there is nothing holding them up.
There is also one that is more adjustable as you work out what suits you.
I’ve put together a four page diagram of how to build your own. Simple or adjustable.
I tried using commercial gas struts instead of springs to push it up but most are designed to move through smaller angles than are needed.
