Stearns & Foster Warranty Claim & Sagging Ruler Protocol
Deconstructs Stearns & Foster 1.5-inch sagging measurement rules, tufted cover metrology, and warranty claims.
1.5-Inch Tufted Metrology
Direct answer summary
Stearns & Foster handcrafted innerspring mattresses require an unweighted depression of at least 1.50 inches (38.1 mm) under Tempur-Sealy warranty rules. Because Stearns & Foster models feature deeply lofted Euro-pillowtops with hand-tufted rosettes, measuring sag requires placing the straightedge across the high lofted tuft crowns, not the tufting button crevices. The measurement must be taken between tufting valleys to measure true foam fatigue rather than decorative button depressions.
Key points
Requires unweighted depression of 1.50 inches or greater.
Must measure across high tuft crowns, not inside decorative button tufting valleys.
Backed by Tempur-Sealy's 10-year limited non-prorated warranty framework.

Trial, returns and warranty: the fine print
Warranty Proration Cliff & Fine Print Analysis
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
Warranty Claim Diagnostic & Measurement Protocol
Unweighted ruler measurement and photographic documentation steps to avoid warranty claim denial.
- 01
Position Ruler Between Tufts
Place your measuring ruler on the flat quilt crown between tufting button dimples.
Watch for: Do not measure inside the decorative button depression; inspectors deduct button depth.
- 02
Check Foundation Frame
Ensure the mattress rests on a genuine Stearns & Foster foundation or rigid platform.
Watch for: Using flexible wire foundations immediately voids Stearns & Foster warranties.
- 03
Submit Photos to TSI
Upload wide-angle and macro depth photos to the official Tempur-Sealy warranty portal.
Watch for: Ensure no fabric stains or burns are visible on the luxury silk-infused ticking.
