We purchased the large planter box 94.5x47x24 and it is huge. Seems to be good quality and easy to put together... but a lot of bolts takes a while. My only complaint = the "cross-supports" that holds the sides in when you fill it are not very strong. If I had known this (or if I buy another one of these) I will create my own cross-side-supports to hold the sides in better when you fill it. As it is... it will "bow" out in the middle when you fill this, just FYI. It seems to hold strong and the bowing out doesn't look like it will be a problem but if you added a few more middle-supports across the unit it should help a lot. Also, FYI, this takes about 3 yards (tons) of soil to fill it unless you have some tree-trunks or other degradable material you can fill in the bottom with. Overall, we are happy with this unit but just a couple things to know before you get started and you will be much better prepared.
