Sealy Posturepedic Cobalt Review

Expert Summary

The Sealy Posturepedic Cobalt is a 13-inch hybrid innerspring firm tight-top mattress. It has a base support layer of innerspring pocket coils with a gel memory foam layer resting above.

This particular model from Sealy is very difficult to find both online and in-stores. As a result, we strongly recommend considering similar alternatives.

Before you make a buying decision on this model, we recommend checking out Saatva's Classic. We think it's the closest premium ultra-luxury alternative. They're also our #1 Best Mattress of 2022.

Firmness, Feel & Comfort of the Sealy Posturepedic Cobalt Review

The Sealy Posturepedic Cobalt is about a 7-8 on a 1-10 firmness scale - which makes it ideal for people that primarily sleep on their back and stomach. Infrequent side sleepers should likely stay away. Your main goal is to find a compatible comfort level that matches your sleep style, body shape & mattress type preference. This is especially true for your long-term health & wellness.

Most people fall into 3 buckets - depending on your (1) weight and (2) sleep preference. These 3 buckets are: (a) light, (b) average, and (3) heavy sleepers.

Light Sleeper: Light sleepers (under 130 lbs) might struggle on a firmer mattress (6-7 a 1-10 firmness scale). You could potentially experience an uncomfortable amount of resistance as you lay on top of the mattress. There is a little give to the mattress, but not a whole lot (especially because you're a little lighter than the average sleeper). Unless you know for a fact that you have sensitive pressure points, this resistance should not aggregavate your pressure points (in a lot of cases, it could help).

Average Sleeper: If you're an average sleeper (130-250 lbs), a medium-firm comfort level is your goldilocks zone. Keep in mind, comfort is very subjective - but a medium-firm is universally popular for a reason. It does the trick most of the time, especially if your weight range falls within 130-250 lbs.

Heavy Sleeper: If you're on the heftier side (>250 lbs), this firmness is your happy place. Unless you know for a fact that your body struggles on a firmer mattress (which is relatively rare, surprisingly). Unless you know for a fact that you enjoy a (1) super soft or (2) super firm mattress, this firm comfort level should be a great choice.

Construction & Design of the Sealy Posturepedic Cobalt Review

The Sealy Posturepedic Cobalt has innerspring pocket coils for support & a gel memory foam comfort layer resting above.

Additionally, the tight-top does a fine job supporting your weight, providing a relatively wide sleep surface and decent edge support.

This hybrid innerspring and tight-top combination is a standard, modern mattress construction. Even in older, potentially discontinued (or very difficult to find) models like this one.

This is a 'tried-and-true' style, even if material quality is potentially lower than more premium, popular (and rightfully so) mattresses online (like a Saatva, Winkbed, or Puffy).

Support & Motion Isolation of the Sealy Posturepedic Cobalt Review

Support & motion isolation for Sealy Posturepedic Cobalt is fair (nothing exceptional).

The bottom innerspring pocket coils combined with the gel memory foam do a fine job dissipating motion transfer across the mattress.

It's safe to say the Sealy Posturepedic Cobalt is likely built to last 3-5+ years (before it's time to replace it). This is one of the main reasons why it's difficult to recommend this mattress.

Availability of the Sealy Posturepedic Cobalt Review

This specific Sealy model, like many, are hard to find online. Availability is unreliable at best.

Large established brands usually release dozens of models (then stop producing them). This creates a confusing and difficult landscape to comparison shop.

Final Thoughts on the Sealy Posturepedic Cobalt Review

The short answer? No.

Best 10 Mattress's editorial team does not recommend discontinued or difficult to find mattresses.

Thus, we cannot in good-faith recommend the Sealy Posturepedic Cobalt.

The good news? There's a fantastic alternative to the Sealy Posturepedic Cobalt.

The Saatva Classic. Saatva is also our Best Mattress of 2022.

Saatva matches or exceeds the Sealy Posturepedic Cobalt in every major metric (in our opinion), including price-to-performance and overall value based on our detailed assessment & analysis of both mattresses.

Breathability & Heat Transfer For Sealy Posturepedic Cobalt

The Sealy Posturepedic Cobalt uses very basic cooling tech in both their top cover and construction. Don't get confused when you see proprietary names. These are fancy marketing techniques to make otherwise normal features appear more sophisticated and better than they likely are.

There are 2 primary factors that affect cooling in a mattress: (1) does MODEL have decent airflow?, and (2) does the top cover and construction wick moisture & dissipate heat?

If those 2 benefits don't exist, heat created by your body at night can trap temperature pockets inside the mattress. These airflow issues create a furnace for anyone laying on the mattress at night. Rising heat in a mattress could potentially cause a loss of REM sleep. Losing REM sleep carries a whole host of other negative health consequences (way too many to list here).

In the case of the , there's a chance small heat pockets like this could form. It's exceedingly difficult to compare mattress models and technologies, so we usually recommend either: (1) calling Sealy directly to confirm specific features of technologies, or (2) consider a luxury online mattress company (almost always a better option). In the case of #2, we strongly recommend taking a look at Saatva.

Eco-Friendliness For Sealy Posturepedic Cobalt

The Sealy Posturepedic Cobalt is not an organic mattress. Eco-friendly? Maybe. It's difficult to measure because eco-friendliness is a very subjective (and often-times a very personal) assessment.

If eco-friendliness is your primary concern, we recommend considering e-commerce brands with much less potential physical footprint (since they have few-to-no physical stores).

The most comparable 100% organic brand we feel comfortable recommending is Zenhaven. Zenhaven is a 100% talalay latex mattress that's flippable and built unusually well for it's price point.

Shipping, Delivery & Returns For Sealy Posturepedic Cobalt

Warranty & Exchanges For Sealy Posturepedic Cobalt

Sealy may allow you exchange, but it depends on the individual retailer.

This individual model's warranty typically relies on the specific law tag label 'code'. Mattress warranties can range from 1-25 years.

Quick tip - always check the 'law tag' on your mattress for extra instructions in the event of a return, exchange or warranty.

Checking your mattress's law tag is a good general practice with any mattress. Some exchange or warranty policies can have strict body impression requirements. For example, if your body impressions don't exceed 1.5 inches, you may not be able to return or exchange your mattress. This is a standard depth that most stores & brands use.

Where Can I Buy The Sealy Posturepedic Cobalt

There isn't much available information about where to buy a Sealy Posturepedic Cobalt mattress. This lack of information policies, too.

You may be able to find the at a physical mattress store near you. We find this to be very unlikely.

Normally, the retailer determines terms for: (1) shipping, (2) delivery, and (3) returns. All 3 (especially shipping) can vary fairly significantly between mattress retailer locations - which also depends on your state.

The above difficulty is why we recommend considering alternatives that you can find online.
