Received them in two days thanks to WayFair's speedy s/h.  Product comes in a medium size box with individual pieces wrapped in plastic or bubble.  I put these two stools together in 5 mins using my own tools, though it does come with a supplied hex wrench much like the ones you get from Ikea.  For the price, I can't complain, and I don't have a single complaint yet as I've only owned these for 1 month. So far I've received nothing but compliments and people think they are worth $200 for the pair! kudos!  Hydraulic system easily brings the stool up and down effortlessly, however, my wife who's 110 lbs can't bring the stool down w/o my assistance.  Stability wise, stool is rock solid, and have gone through people of varying weight and height from 60lbs to 180lbs w/o a hitch.  Buy these with confidence. I bought the ivory color, easy to clean with standard household cleaners.  

Pros: Price point, easy to assemble, durability
Cons: Must weight 115 plus pounds to bring it down
