Very skeptical about buying a king size box spring that you needed to assemble but after reading the reviews loving the price and only a few days before receiving a mattress from Wayfair that we loved I decided to go for it! So glad I did. We are on the east coast it was coming from California in the heart of the pandemic so it took quite a while to ship but it was so worth the wait my husband had it together  in less then 20 minutes, the materials are very good quality and it’s very sturdy but light weight. Will definitely order mattress and box spring for guest bedroom from Wayfair we are very pleased.
