Easy to assemble with one exception - there are plastic straps held in by staples under the bench - don't do what I did and cut off the straps.  If you do that, the staples are very hard if not impossible to remove!  Use the straps to gently pull out the staples.  I cut the straps first and was left with sharp pieces sticking out of the staples and had to cover with duct tape - it's not a big deal but with little kids, I was worried little hands might reach under the bench and get poked or cut by the plastic strap remnants.  The bench itself was super easy to put together with a power drill with the right size bit and is very solid.  Love it!!
