Imperial 620 Plush Top Memory Foam Mattress

620 Imperial Plush Top Innerspring Mattress

Mattress and Foundation sold separately.
Foundations may be selected at the bottom of the page

The luxurious feeling of fully foam encased Individual Coil springs and real foam edge support with the added comfort of a removable Plush Top make this Sustainable Eco friendly modular design a great value and the ideal sleep system.

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.
