The Sentora Ultra Firm Mattress by Snowdown Mattress Inc. delivers premium tight top support for sleepers who demand proper spine alignment. This professionally engineered pocket coil system puts solid back support exactly where you need it, proving that true comfort starts with proper posture.

7-Zone Pocket Coil System For Targeted Back Pain Relief

The Sentora Ultra Firm stands above ordinary mattresses with its precision-engineered 7-zone pocket coil system. Built with 972 individually wrapped 13-gauge extra firm coils, this mattress holds your spine in perfect alignment throughout the night. The result: less morning pain and more productive days.

Unlike standard mattresses that sink and sag, the Sentora features surround support foam encasement and high-tempered coils that maintain rigid structure year after year. This makes it perfect for back pain sufferers, sleepers who need extra firmness, or anyone who prefers a solid sleep surface.

  • High Density Support Layer: 7-inch High Density Foam-HQ delivers the foundation for proper support
  • Luxury Quilted Surface: Tuck and jump pattern with 3/8" medium firm foam and 20oz poly wrapped in premium stretchy fabric
