Signature Sleep not only sells three separate lines of mattresses, but also folding guest beds,
sofa sleepers, pillows, foundations, and other furniture. The brand’s diverse range of products means there is something for every type of sleeper of every body type. In this review, I analyze to determine whether the Memoir 12-inch--firm memory foam is one of the best mattresses that supports and lightly cradles heavy people.

The Signature Sleep 12-inch Memoir Mattress is affordable and easy to set up. It's a great option
for heavy, large or obese people as well as individuals who are on a budget.

With a full 12 inches, the Signature Sleep Memoir is among the densest in the industry. The mattress sleeps firm, while cradling your body as a good memory foam should. People with heavier body types feel supported without sinking into the mattress.

On a scale of 1- 10, with 10 being the firmest, the Signature Sleep Memoir 12-Inch is at 7.5

Warranty + Return/Refund Policy

Signature Sleep offers a 1-year Limited Warranty that covers defects in workmanship and materials, but not sagging or other side effects of normal wear. The mattress is easy to care for and should be rotated twice annually.

The limited 1-year warranty is shockingly low compared to the industry standard of 10- and 20-year warranties. At best, this mattress may last 5-7 years.
