Nectar Mattress Foundation review

Nectar's Mattress Foundation is less a box spring replacement than a foundation and bed frame in one. It has dark grey upholstery, midcentury-style legs and a slatted top, and Nectar lists the materials as solid wood, metal and a polyester blend. With legs it stands 15 inches tall and leaves 8.0 inches of clearance for under-bed storage; the legs are removable if you want to set it inside an existing frame. Nectar estimates a 20-minute build. A queen cost $349 when we checked, shown against a $608 total value, and it ships in 1 to 2 days. Nectar gives the foundation a 60-night home trial, free shipping and returns, and a 2-year warranty. It suits buyers furnishing a room from scratch. If you already own a frame with rails, a plain foundation from Sealy, Brooklyn Bedding or Bear costs about $100 less for a queen.
