Firewood racks are great tool to help you get more mileage out of your firewood. Elements like wind, snow, rain, and even the weight of the wood will wreak havoc on weaker models. However, each way is designed to do one of two things. This is just like firewood rack. Firewood needs to cure in order to burn properly.
Since they raise the wood off the ground, it allows wind and sun to more easily dry out the wood compared to other methods. This is similar to plans. They offer better protection from the rain and snow. This is a nice luxury to have so be sure it is built into your buying decision.
They are not designed for curing purposes and, it is critical that you use ones that let the wood breathe and do not fully cover the wood. Which is similar to firewood cover usually. A good firewood rack will not only allow you to neatly stack your stored logs, but it also promotes drying and cross ventilation. Although you may not think that you will need to move you rack around a great deal, most people end up having to move theirs enough to give the weight of it some consideration.
