Sealy Mattress Warranty 1.5" Sag Ruler Test

Guide to Sealy Posturepedic 1.5-inch sagging warranty inspections, string tests, and foundation rules.

1.5-Inch Industry Standard

Direct answer summary

Sealy Posturepedic limited warranties mandate an unweighted indentation of 1.50 inches (38.1 mm) or greater for innerspring and hybrid models. Under Sealy's warranty guidelines, impressions under 1.5 inches are classified as normal body contouring. The measurement must be taken with the mattress resting on a certified Sealy foundation or rigid platform with proper center floor support legs, using an unweighted string and calibrated ruler.

Key points

  • Mandates 1.50-inch unweighted sagging threshold across innerspring and hybrid models.

  • Depressions under 1.5 inches are excluded as normal body settling.

  • Requires a matching rigid foundation with center support legs on Queen and King frames.

Checklist

Warranty Claim Diagnostic & Measurement Protocol

Unweighted ruler measurement and photographic documentation steps to avoid warranty claim denial.

  1. 01

    Lay String Across Seams

    Stretch a straight string across the tape edge directly over the deepest hollow.

    Watch for: Do not let the string touch the quilt crown; hold it firmly at edge bindings.

  2. 02

    Insert Ruler Perpendicularly

    Drop a ruler into the hollow and record the exact fraction of an inch.

    Watch for: Never apply downward pressure on the ruler to push into the foam.

  3. 03

    Document Foundation Legs

    Take photos of the bed frame showing center support legs touching the floor.

    Watch for: Missing center legs will cause instant claim rejection by Sealy claims adjusters.
