Waking up and feeling like you haven't slept is common when you have an uncomfortable lump in the middle of your mattress. Even if you can't afford to replace your mattress just yet, there are things you can do to make your bed more comfortable while you save up some cash. You probably can't remove the lump completely, but you can make your bed a more restful place.
Things You'll Need
Thin plywood cut to size of mattress
Flip and turn the mattress. This helps even out the lump and increase usage on both sides of the mattress for a more comfortable sleeping experience. You should flip and turn most older mattresses at least every six months.
Purchase a mattress pad. You can put a mattress pad on top of the mattress to make the mattress feel brand new and help smooth out and fill in any lumps. A foam or "egg crate" mattress topper provides a thick cushion on top of the existing mattress.
Place a piece of thin plywood between the mattress and the box spring to help fix the lump and keep the bed stable. The wood helps provide support for your body while you sleep and makes the lump less noticeable.
Add some comfortable sheets to make a lumpy bed feel more welcoming. Splurge on flannel, satin or jersey sheets to make the bed more cozy. Pile on a thick comforter to help enhance your night of rest and make the bed feel nicer.
