I bought my mattress about 4 or 5 years ago.
Gap between mattress and footboard.
In many cases when there s a gap between the headboard and mattress it is simply because the box spring isn t positioned correctly.
Wedge shape fills gaps up to three inches.
Prevents arm and leg entrapment.
The number of boards you use depends on how wide the gap is.
Short footboards can either have the bedspread tucked behind the footboard or allowed to cover it.
Check pieces and determine measurements.
Diy headboard mattress gap filler so full disclosure this gap filler technically goes between the foot board and the mattress not the headboard and the mattress.
If you prefer you could push the mattress all the way up to the headboard and fasten the stop gap board s to the footboard instead.
It was supposed to be a standard king.
Tall footboards require that the bedspread be tucked into the gap between the footboard and the mattress.
It pushes the mattress all the way up to the headboard so that the gap doesn t occur at all.
Works when side rails are raised or lowered.
Closes space between mattress and headboard footboard.
Step 3 remove both the mattress and box spring if this still doesn t fix the situation.
