Easy to assemble.  Took me under 3 hours.  Great value!  Bought it for a sleeping porch.  Tried it out myself last night.  Plenty of room, easy to un-fold and fold it back up.   3 small caveats:  (1) assembly guide was very well-done, lots of diagrams, everything is well-labeled and color-coded.  But it needs to mention that putting the top knobs in their grooves first makes aligning the bottom knobs in their grooves much easier. (2) Mattress gives off quite a smell - sort of like saw-dust -- hoping this will fade quickly.  (3) Mattress is very heavy:  potential buyers should understand that 2 people required to pick it up.
