Saatva Friends for Life Limited Warranty Policy
Manufacturer Policy
Engineering breakdown of Saatva's 3-inch maximum slat spacing rule, center support beam mandates, and warranty fine print.
Under Saatva's official warranty terms, placing a Saatva Classic or HD mattress on a platform bed with slat gaps exceeding 3.0 inches (76.2 mm) voids all warranty coverage immediately. In addition, Queen and King bed frames must include a rigid center support spine with at least one vertical floor leg (two for King). Slat gaps greater than 3.0 inches allow pocketed coils and dual-tier innersprings to bow downward, causing artificial sagging.
Slat spacing must not exceed 3.0 inches (76.2 mm) edge-to-edge.
Queen and King bed frames must have a rigid center support rail with vertical floor legs.
Using traditional flexible-wire box springs or bowing curved slats voids all warranty rights.

Calculate proration cliffs, test unweighted sagging ruler thresholds, and verify foundation slat gap compliance before submitting a claim.
Mattress warranties advertised as "25-Year" or "Lifetime" typically undergo an actuarial transition into a steep proration cliff after Year 10. Consumer defect claims require rigid straight-edge depth proof and strict foundation compliance.

Checklist
Unweighted ruler measurement and photographic documentation steps to avoid warranty claim denial.
Use a tape measure to check the gap between every wooden slat across the bed frame.
Watch for: Never place a Saatva mattress on slats spaced 4 or 5 inches apart.
Ensure the vertical center leg firmly contacts the floor without wobble or float.
Watch for: Do not let the center support leg rest on thick rugs without leveling pads.
If your platform slats are spaced wider than 3 inches, lay down a solid bunkie board.
Watch for: Never use raw, unsealed plywood sheets that trap sweat moisture.
