The 620 Imperial Plush offers great value and shares the primary benefits of the 675 Imperial: Exceptional comfort with interchangeable replaceable component parts. Our supportive Marshall Individual Coil system conforms to each sleeper’s individual shape better than other spring systems, isolates motion transfer and reduces noise because coils are not wire tied or connected metal to metal. As a result this mattress provides firm support for sleepers of all sizes and shapes better than any other spring system on the market.

You can upgrade your 620 into a 675 by adding latex or memory foam comfort layers. Increase firmness by exchanging the quilted cover for a stretch cover at any time!

  • Individual Coil construction provides support by conforming to each sleeper’s size and shape
  • Foam encased Individual Coils reduce motion transfer and noise.
  • Real foam edge support provides a full width edge to edge sleep surface and seating edge support
  • Bed comes completely apart for proper cleaning
  • Cover panels and 1” foam encasement reflex overlay are removable, interchangeable and available for separate purchase
  • Naturally Anti-Bacterial, our ALOE VERA fabric treatment makes material hygienic and very soft
  • Double the comfortable service life of your bed by replacing worn or soiled bed parts instead of replacing the complete mattress.
  • Reduce your Environmental Footprint with our Sustainable bed systems: Renew, Reuse, Prevent solid waste
