I read the reviews for several different twin mattress before ordering this - and it was just as nice as everyone said - and soooooooooo easy to handle!! I had to carry this up to the 3rd floor, so I opened the box up in the living room, and then carried the pieces upstairs to assemble. MUCH better then trying to maneuver a mattress around corners, up the stairs and through doors. The next time I need a larger size mattress, I'm going to order this same type!! It was simple to assemble in a small room - and so comfortable. 5 stars, home run.
Oh - be prepared for a surprise - the package is "way too small!!" But when you open and unwrap it, the 3 spring "biscuits" go --=BOING=--, and pop up. The cover also expands as soon as you open the vacumn package. When I have to move it, I'm going to disassemble it, stack the 3 springs and tie some cord around. Drop them in a big trash back, fold the cover and stuff it in - I'll be able to get it down stairs and into the back of the car - not something I'd try with a regular mattress.
Oh - and sleeping on it is 100X better then the foam mattress on my daybed frame.
Great value, fantastic engineering
