Casper Foundation review

Casper's Foundation is a straightforward wood slatted base that makes the most sense alongside a Casper mattress. The frame and slats are solid and/or engineered wood, the outside is wrapped in woven upholstery, and every size stands 7.5 inches tall; a queen measures 79 by 59.5 inches. A queen cost $314.10 when we checked, 10% off a $349 regular price, and Casper ships it free by UPS in 1 to 2 business days. The trial is 30 nights on its own but extends to 100 nights if you buy it with a matching mattress, which is the best reason to choose it. Casper covers it with a 2-year limited furniture warranty and sells spare foundation pins if one goes missing. The limits: there is no low profile version for tall mattresses, and Casper says it should sit on a sturdy metal frame rather than directly on the floor.
