I bought 2 of these two years ago and am delighted with them. One is against a wall, one is freestanding.   Love the extra depth and solid feel.  I have a 10 ft kayak on top of each and lots of heavy "garage stuff" on the shelves.  Added two L-brackets to hang long ladder on one.  I raised my lowest shelf to allow heavy things on the floor. Need more?  Get creative and attach a few 2X4s.  Great shelf!
