The Birch Log Futons are made from thick 6" diameter birch that are mortised and tenoned together. This type of construction ensures that the futon is solid and sturdy. The front-operating futon frame is made from solid wood which is screwed and glued together (other manufactures use staples and no glue). Each log has its own unique look (which includes unique cracks, knots, and checking) and every futon comes with a limited lifetime guarantee against defects in material and workmanship. Each futon comes with a black or green 8" innerspring mattress that offers superior support while sitting or sleeping. Some assembly is required. Futon cover shown is not included. Made in the USA.
