Zinus has been in business for more than 20 years and calls itself the “pioneer in comfort innovation.” With nearly 100 U.S. patents, Zinus works to continuously improve its products. It takes its customer reviews seriously, and its willingness to adapt and produce customer-driven mattresses are commendable.

Though the Performance Plus is highly recommended as one of the best mattresses for heavy, large or obese people, the mattress has its limitations. See why in my review below.

      handle. (See video)
  • The mattress is delivered compressed and rolled in a box.
  • The Zinus must be unpackaged within 72 hours of delivery.

      it requires turning every few months. Some users find they need to turn it every time they wash
      the sheets for the mattress to retain its shape.
