Expert Review By Jed
The Sealy Posturepedic Premier Hybrid Cobalt is the entry-level model from the Hybrid collection. The King size of this model is designed for couples who want a spacious mattress with high-end comfort and support. The Cobalt scored a medium-firm Comfort Scale rating of 4, having a firm overall feel with good contouring capabilities. I recommend this mattress to back and stomach sleepers, but suggest side sleepers go with something softer to avoid discomfort in the hips and shoulders.

The Cobalt relies on the Zoned Sealy Embrace Premier Coil System for core support. This system features a series of individually wrapped coils that deliver solid support as well as effective contouring. This coil system is zoned, meaning there are more coils in the center third of the mattress to improve support and durability where you need it most. The individually wrapped design is important for couples as it transfers much less motion than tied coil designs.

On top of the coil system, a layer of SealyCool Gel Memory Foam is added to the center third of the mattress to bolster support to the vital lower back area. On top of that, a layer of SealyCushion Extra Soft Foam is used to provide some padding and a soft layer that will contour to the curves of your body. Lastly, the top layer of the Cobalt is a full layer of SealyCool Gel Memory Foam that effectively reduces pressure points so you toss and turn less. SealyCool Gel Memory Foam is very durable, allowing the sleeping surface to maintain its showroom comfort for a long time. It also helps reduce motion transfer, and SealyCool Gel Memory Foam includes phase change material which is able to maintain a temperate sleeping surface all night long.

In summary, Sealy achieved a really good balance of performance and affordability with this model. The King size Sealy Posturepedic Premier Hybrid Cobalt is a great choice for couples who want a spacious, medium-firm mattress. It boasts the benefits of both innerspring support and memory foam at an affordable price point. It also comes backed by a 10-year warranty, so you can be confident in your investment.

Awesome Service & Great Mattress
Its been very easy to work with US Mattress, on time delivery and this bed is amazing.

Amazing Bed
It has only been 3 weeks but the Cobalt mattress is an amazingly comfortable bed. Our prior bed you heard and felt every turn, with this hybrid mattress that has all gone away. If you are coming from a spring mattress it takes a few days to adjust, but this bed is highly recommended for the price and comfort. Lastly we were concerned it would be too firm since we sleep on our sides and it's been great. There is an odor from the mattress that is pretty strong for a few weeks but it does fade away

Great support, great company
Love the bed, support is excellent and little wave movement. Other reviews claiming sagging not apparent to me but have had the bed for only a month. US Mattress was great to work with, easy to order, shipped on time, delivered and set up quickly and cleanly and met their appointment for delivery right on time, all at a good price. Couldn't be happier with my purchase so far!

Tried out the Posturepedic hybrid kelburn elite at a brick & mortar store and really liked it. This is the same mattress (under a different name) for ~$200 less.

I have tried the mattress in a store and it was the one I was looking for. Firm, for the back but soft. The memory foam was not too "memory" which is the reason I choose it.
