Solid Wood Frame Reinforced with Metal: Our rolling elevated garden bed is made of classy, carbonized fir wood and reinforced with double-layered metal corners. The corners are powder coated to provide extra resistance against water. Together these materials add up to a 77 lbs. weight capacity you can wheel almost anywhere.Trellis Trough: This raised flower bed is a 2-in-1 planter box and trellis. Use it inside or bring it outdoors. It's excellent for climbing plants like grape vines, tomatoes, and sweet potatoes or decorative delights like ivy or morning glory. Our trellis is also excellent indoors as a place for keyrings, string lights, and other knickknacks.Four Wheels for Photosynthesis: With our above ground garden box, you won't have to stay in a place, that's because it comes with four universal wheels (two with brakes). Have an herb planter that you can move in and out of the sunroom. Offer plants time in a greenhouse. Take it out for the winter, then get it out in the garden for spring.Self-Draining Planter: Why worry about excess water if it can handle itself? Keep soil fresh and protect your plants from water logging with a self-draining design. Internal non-woven fabric helps our trellis planters stop soil from falling away (please use something of adequate size under it to catch falling water when using it inside).
