Step up to Memory Foam

by Jed Harrington

The first mattress in the Crown Jewel line to feature gel memory foam, the Sealy Crown Jewel Geneva Ruby Firm is a quality mattress with some of the best features in the market today with an overall firm, yet still forgiving comfort.

Firm, but not too firm

The combination of CertiPUR US certified foams in this mattress stack up to an impressive 5.5 inches comfort. The different densities of these foams will bring about that firm, but not hard feel that people are typically looking for when they say they want a supportive mattress.

Best in Class

The Geneva Ruby is the first mattress to feature the top of the line coil system in the Crown Jewel line - the Sealy Stability Plus Coil - hundreds of independently wrapped coils provide exceptional support along every inch of your body due to its great conformability. The hour glass design also provides a smoother transition from initial comfort to sturdy, deep down support. Due to its individually wrapped nature, this mattress features both great motion separation between partners as well as adjustable base compatibility.


While not something you immediately notice, the handles equipped on this bed will come in handy when it comes time to rotate your mattress. We recommend rotating every 3-6 months to ensure an even wearing of the foams and to maintain that showroom feel for 10+ years.

Super Supportive Edge

The DuraFlex Edge is a coil based edge support system. This means there is additional support along the outside of the mattress to avoid feeling like you might roll off the mattress, but in addition to that, since it is coil based, there will not be any heat build up as there might be from a foam based edge support.

Back and Stomach Sleepers

Overall, this is the sweet spot of the Crown Jewel line with ample amounts of sleep inducing foam including gel memory foam, an upgraded coil system, the supportive coil based edge, and handles while not breaking the bank. If you are looking for a firm mattress that fits all those criteria, I highly recommend the Sealy Crown Jewel Performance Geneva Ruby Firm.
