Sealy Posturepedic Hybrid Cobalt Firm Mattress – Review

Cobalt Firm from the Posturepedic range of Sealy mattresses is a medium-firm mattress; it can provide some contouring but gives an overall firm feels. The mattress uses Zoned Sealy Embrace Premier Coil System for core support. With the zoned coils in the mattress, the sensitivity of the partner’s motion on the bed is reduced, which can enable you to have a comfortable and deep sleep.

The mattress can help to alleviate a backache due to the layer of SealyCool Gel Memory Foam technology. This layer enables the mattress to give enhanced support to the lower back area. Moreover, it eliminates pressure points to provide relief from pain in the back and shoulder area.


Cobalt Firm mattress keeps the body temperature in control with its airflow system. This particular feature keeps the mattress fresh and clean for a longer period. It is a firm edge-to-edge mattress that provides high-end support. Moreover, it combines the benefits of both the innerspring mattress and memory foam for enhanced comfort.

The price range is reasonable for a mattress with exceptional features. Furthermore, it comes with 100% money back guarantee; you can claim a refund if you aren’t satisfied in the 120 nights in-home trial the makers are offering. Another benefit of ordering Cobalt Firm from Sealy is that you do not have to pay delivery charges. The mattress will be delivered to you in maximum two weeks across the US.


The mattress is on the firm side; therefore, it is not fit to be used if you are a side sleeper. It can cause neck, back, and joint pains for side sleepers due to its firmness. Another demerit of Cobalt Firm from Sealy is the initial order, which can cause discomfort for the first few days.


The final word for Sealy’s Cobalt Firm is that it is perfect to be placed on your bed if you are a back or stomach sleeper. It is medium firm, which enables it to provide enhanced support to your back and alleviate your backache. However, if you are suffering from joint issues or are a side sleeper, you shouldn’t consider this mattress. The price of this mattress is a little on the higher side but is worth the features it boasts of.
