Eco-Friendly Plywood Furniture. Making solid wood furniture can be an extremely wasteful process. Just think about the fact that a log is round while a wood board is rectangular. When a rectangular board is cut from a round log, all that wood in the circumference is wasted. Sure, some of it is recycled into chip-board, but chip-board is mixed with an almost equal volume of urea formaldehyde resin, an extremely toxic substance. Not cool and not healthy. Fun to Assemble. All Legare panels use a patented locking design, so there are no screw holes to line up, small hardware pieces to lose or complicated instruction steps to follow. Assembly is fun, fast and simple.
