What is not covered on a mattress warranty
- A mattress warranty does not guarantee that you'll "like" the mattress...
- It does not guarantee that you'll still think it's comfortable 10 years later...
- It does not cover damage caused by jumping on the mattress, or damage caused by moving...
- Size discrepancies of up to plus or minus 1 inch
Measuring the DipPlace a broomstick (string may also be used as a substitute) from one side of the mattress to the other. Using a ruler, measure the distance between the lowest point on the mattress surface to the bottom of the broomstick. If the distance from the bottom of the impression to the top of the broomstick exceeds 2 inches the mattress body impression is not within the advised body impression depth. If the impression does not exceed 2 inches there is no need for concern. Please note that when measuring a memory foam mattress or mattress with memory foam topper, a few hours may be required before the foam fully decompresses to its natural state.
Remove all bedding from your mattress including sheets, pads and foam toppers. The original top of the mattress needs to be exposed so you can accurately measure the depression.
Smooth the top of the mattress with your fingers. This eliminates any possible wrinkles in the fabric that could cause the measurements of the sagging to be inaccurate.
Lay string across the width of the mattress so it reaches from one side to the opposite one. It should cross over the deepest part of the depression. Secure one end of the string to the edge of the mattress with a strip of painter's tape which does not leave a sticky residue on the fabric when it's removed.
Walk to the other side of the bed and gently pull the unsecured end of the string until it is taut. Secure your end of the string with a strip of painter's tape. While most of the string rests on top of the surface of your mattress, it does not make contact where it crosses over the sagging portion.
Pull the steel measuring tape so it extends a few inches from its housing. Place the end of the tape so it touches the bottom of the sagging portion of your mattress alongside the string. Hold the housing upright at a right angle to the mattress. Read the measurement on your tape where it intersects the string. This tells you how much your mattress is sagging.
