Bear Foundation review

The Bear Foundation is a simple boxed wood base at a low sale price. Bear builds it from Canadian spruce with gray upholstered sides, puts the wood slats 4 inches apart and adds a firm center rail. The two slat packs unroll and fasten with hook-and-loop strips, and Bear says the 3-step assembly takes under ten minutes with no tools. Heights are 7.5 inches or a 5.5-inch low profile, and Bear publishes exact dimensions and weights for every size; a queen weighs 69 lbs. When we checked, a queen cost $259.35 with the BF35 code, down from $399.00, and ships free by FedEx in 3 to 7 business days. Bear says the foundation needs a bed frame and suggests its own Bear Frame. The weak point is coverage: a 1-year limited warranty is far shorter than the 10 years Purple, Sealy and Avocado offer, so expect to rely on the frame and your own care.
