Our Queen size all wood foundation is designed to work best with latex beds, memory foam mattresses and poly-urethane foam mattresses. It can also be used on standard spring mattresses. It measures 59" x 79" and fits all standard Queen size mattresses. We pre-assemble each and every wood foundation to assure proper alignment and then dis-assemble it for shipping purposes. Assembly is easy and is explaned in detail on the home page for this item. The design outperformes other foundations because we use more wood slats and our slats are wider than our competition making this Queen wood foundation a great value as well.
