If you prefer a traditional look than this Upright Series aquarium stand is the one for you. These black aquarium stands are made of Medium-Density Fiberboard (MDF). Two distinct advantages of MDF are its water resistance and its overall strength. The Ready-To-Assemble Construction of these aquarium stands result in increased strength and stability by using Metal-To-Metal locking cam assembly fasteners. The solid tops offers greater versatility over those with mere “lip only” construction, allowing these aquarium stands to be safely used with a variety of tanks, or other pet habitats. Available in seven sizes, 26 gallon, 29 gallon, 38 gallon, 46 gallon, 55 gallon, 65 gallon, 72 gallon or 90 gallon.
