The Detail That Makes It Work
Two Straps, So It Never Slides Down
Two elastic straps are sewn into the back. If you already have a headboard, slip them straight over it. The pillow is then anchored in place, it cannot tip forward or slide down behind the mattress, and the hard surface you used to lean on is now covered in soft fabric.
If you do not have a headboard, stand it against the wall. It is wide and deep enough to hold itself upright and simply becomes the headboard.
No tools, no brackets and nothing fixed to the wall, which makes it one of the few headboard upgrades you can actually do in a rental.
