If you have one side of your bed against a wall and are having trouble getting the bottom sheet wrapped under the mattress on that side, there are a few tricks you can try:
Use a long tool: Find a long, sturdy object like a broom handle, mop handle, or a long wooden stick. Slide it between the mattress and the wall, positioning it parallel to the edge of the bed. With the sheet gathered on the tool, you can easily tuck it under the mattress.
Utilize a makeshift hook: Take a wire hanger and straighten it out, leaving the hook at one end intact. Bend the straightened part into a 90-degree angle to create a makeshift hook. Slide the hook between the mattress and the wall and use it to grab and pull the sheet underneath.
Use elastic straps or sheet suspenders: These are adjustable straps with clips or fasteners that attach to the corners of your fitted sheet. They help keep the sheet in place and prevent it from slipping off, even if you can't tuck it under the mattress on one side.
Lift the mattress: If your mattress isn't too heavy, you can try lifting the edge slightly to create enough space to tuck the sheet underneath. You may need assistance from someone else to hold the mattress up while you tuck the sheet in.
Adjust the position of the bed: If possible, consider moving the bed slightly away from the wall, leaving a small gap between the mattress and the wall. This will give you enough space to easily tuck the sheet under the mattress on that side.
Remember to be cautious while attempting these tricks to avoid any injuries or damage to the bed or yourself.
