Box Spring
The mattress pad is meant to be placed on top of the mattress and directly under the bottom sheet.
To the bottom of the foundation or the top of the mattress?
The movie Bed Knobs and Broomsticks has a flying and time traveling bed (that includes a flying mattress).
When you say mattress that is the top. Boxspring is the bottom. So im guessing you have mattress and boxspring extra long. The answer is yes. A twin extra long mattress will fit a regular twin bed frame. The length is just longer not the width.
The mattress on my day bed is 37"X74".
The mattress will be 60 inches (same width as queen bed mattress) by 72inches (8 inches shorter than queen bed mattress).
Bed
No. Especially if you have a thick mattress. The f/q comforter doesn't even come to the bottom of the mattress or cover the pillow area.
The structures forming stomach bed are mattress, bed sheet,pillows,blanket,pillow covers,cushions etc.
An air mattress is a mattress inflated with air, and used as a temporary or permanent bed.
The foundation of a bed is what you put the mattress on top of, it is the bed it's self not including the mattress, headboard, foot board or any bedding.
Yes. A toddler bed mattress is the same size as a standard crib mattress. Many cribs are convertible and can be transformed into a toddler bed using the same mattress.
