Two general types of wicker dresser models exist: dressers made with natural fiber wicker, and dressers made with synthetic fiber wicker. Synthetic fiber wicker is basically made of plastic woven in a similar manner as natural wicker, which is made from plant fibers. You can start choosing the best wicker dresser by determining which material you want for your dresser. Synthetic wicker is likely to be less expensive, and it is less susceptible to water damage and mold, though it is sometimes not quite as attractive as natural fiber wicker. Natural fiber wicker can be more expensive, however.
Once you have determined which type of wicker dresser you want, measure the space in which the dresser will be placed to help determine how large of a unit you can place there. Dressers come in a wide variety of shapes and sizes, so it is likely that you will be able to find a wicker dresser that will work with any space, but knowing the dimensions of the space will help you determine which size and design will work best. Be sure to consider how much clothing or other items you intend to store in the dresser as well so you can decide how large of a dresser you will need in relation to how large of a dresser will reasonably fit in the space.
Sometimes wicker is combined with other materials during the construction of the dresser. Solid wood, for example, may be the material of choice for the frame of the wicker dresser, while the drawers and dresser top may be made of wicker. This combines the visual appeal of wicker with the strength and durability of solid materials such as wood or even metal. Be ready to pay a bit more for such a dresser. The durability of the dresser, however, may mean the dresser will last significantly longer than a dresser made exclusively from wicker.
The weave of the wicker dresser should be tight enough that the individual fibers will not loosen and weaken the overall structure. Test the weave by trying to move individual fibers with your fingers. The fibers should not yield at all, or at the most very slightly, when you try to move them. Check around joints in particular for strength in the weave, and be sure to inspect the entire dresser for fibers that may be splitting or otherwise peeling before you purchase the unit.
