You say you the bed is used in its flat position.

Solution 1 –

Position the head of the bed against a wall or an item of furniture, so that the pillow does not slide off.

From the photo it looks as though there is room to turn the bed by 90 degrees and use the wall. If not, remove the clutter in the corner behind the bed.

Solution 2 –

Sleep the other way round, so that the metal hoop at the 'foot' can retain the pillow.

If that isn't enough support, stand a sheet of MDF at that end, drill some holes, and use plastic ties to secure it to the metal hoop and the legs. You now have a makeshift headboard.

How do I keep pillows from falling off an adjustable bed?
First, you can use pillow holders, clips or straps specifically designed for adjustable beds to secure your pillows in place. These pillow straps typically attach to the bed frame and keep pillows from shifting. Consider also placing a non-slip mat or gripper fabric beneath your pillows to prevent slipping. To stop pillows from falling off an adjustable bed, you can try a few strategies. Choose heavier pillows, as they're less likely to move around, or use pillow shams with more fabric. Lastly, adjusting the angle of your adjustable bed to a slight incline can also help in stopping pillows fr

I can think of a few options:

  • Fit a headboard of their own choosing

  • It should be relatively easy to sew a couple of bands of elastic onto a pillow case so that the elastic goes around the mattress. If you're having trouble envisaging what I mean, think about a watch with an elasticated strap. The strap hugs your wrist, and the face protrudes. In the same way the elastic hugs the mattress and the pillow in its case protrudes

  • Consider sewing the pillow case to the bed sheet, if they don't want to change the aesthetic of their sheet/case color matching regularly

  • If their sewing skills aren't up to this and nowhere locally can help, consider taking a pillow case and make two cuts in the bottom (the bit that touches the mattress when it's in sleeping position) near the closed end. Thread a belt, rope, strap or similar fastening into the open end of the pillow case and out through each hole and then flip the whole lot over and strap the pillowcase to the bed, then fill with a pillow

  • perhaps the simplest solution, if they want to go for it, would be to put the bedsheet over the top of the pillow when making the bed

Answer (1 of 2): I use 6 pillows on my side (my wife uses 2) and I don’t lose them. Maybe you are using too many. Maybe you need an older pillow that has been flattened a bit to replace one of your big fluffy pillows. I use a very old, very flat pillow to cover my head on very cold nights.
