Safe Space to kickbox while sleeping (bedding)

This is Shelia frfr. Gotta get safer bed/furniture for mother. She moves around a lot and has even raised up completely in her sleep. She fell again today and even though nothing is broken or fractured I fear for her safety. We are trapped in this little apartment but I have found some amazing pieces that will be comfortable and fit in the space that's available. I would never ask for anything if I could do it myself so if your input has to be a temporary loan I will take and appreciate that as well. Trying to get this done as soon as possible so any and all assistance will be greatly appreciated.
