I ordered 2 blue and 2 yellow.  They were pretty easy to put together. All that is needed is a screwdriver and wrench.  These chairs are light weight and supposedly cedar wood.  The plus is that they are easy to move.  I am not sure how they will last over time as it is made in China stuff, so I am suspicious.  Probably should have dug deep to buy really good ones, but needed 4 so went with these.  Time will tell, but they look nice and they were fairly cheap.
