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. 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.
