Spent a little more to buy this 4x4 rack rather than some other similar products and I'm glad I did.  The unit is easy to assemble and is solid.  I've already stacked it with wood, over stacked actually as It's about 5.5 ft high, and I have no concerns about it not being able to hold the load for an extended period of time.  The cover is a thick canvas material that should hold up well.  I did have one issue, my rack showed up without hardware.  I called Woodhaven (mfg) and they were very disappointed.  They sent them out that day with a couple firestarters as an apology and two days later they were in my mailbox.  Great customer service which is why I'm buying an 8 footer today.

Pros: Sturdy, attractive, easy assembly
Cons: none
