I fell out of bed last night, first time ever. It wasn't my regular bed. One of our grand-daughters had taken up that space, and I was relegated to a spare room.
The mattress is long past its use-by date, and there's diminished support at the edges. I rolled over in my sleep and got a rude awakening when I landed on the floor, hurting my right hip.
That was our previous mattress and it was the reason we splashed out on getting a really good replacement. After all, if you spend one-third of your life in bed, you might as well make it as comfortable as possible.
