I purchased this unit to replace another brand of lesser quality and price that finally died. Assembly instructions are not very good. I spent most of my time trying to figure out how to attach the wheels (go figure). I should have just took a stab at it on my own without the instructions as that is what I finally wound up doing. I am very pleased with the quality and functionality of the unit. My wife and I are going to enjoy this addition to our family. Especially since we are spending much more time at home these days. :)
