HTS Verdict

The Sealy Posturepedic Optimum Radiance Mattress will grant lucky sleepers a comfortable, cool night’s rest without being interrupted by your partner.

Backed by a trusted brand and a long warranty, this mattress may not have the lightest price-tag, but it sure is worth every penny.

The Sealy Corporation has once again outdone themselves with their Sealy Posturepedic Optimum Radiance Mattress, a bed that has twice the lifespan of its earlier versions, as well as cooling gel integrated into every layer for the best night’s sleep you can imagine.

Even tropical nights will pass in blissful slumber thanks to the three different layers infused with gel.

Of course, every mattress has a few downsides. It may be hard to find the Sealy Radiance size you’re after, some retailers only have them available in Queen,  an aspect we found very unfortunate as this immediately limits the audience for what is ultimately a mattress worthy of consideration.

On a more practical level, we also feel that the overall hardness of this mattress might lean more toward the firm side rather than to a plush feeling. While this is good news for those who like to sleep on a firm mattress, lovers of all things soft are left disappointed.

However, is this truly a reason to consider not getting the Sealy Radiance? We made sure to sleep on it and came back with our final report.

After reading, we’re sure you too will understand what makes this mattress the stuff of dreams.

Sealy Posturepedic Optimum Radiance Mattress: The Details


The following dimensions and weight are for a Queen-sized mattress.

Please note that the Sealy Posturepedic Optimum Radiance mattress is only available in the Queen size and will not properly fit bed frames deviating from these particular dimensions.

  • Product Dimensions: 80 x 60 x 11 inches.
  • Hardness: Cushion Firm (As described by Sealy, this is somewhere between plush and firm.).
  • Item Weight: 76 lbs.
  • Mattress Composition: Cooling gel foam, memory gel foam, and Opticore proprietary gel.
  • Cover: Non-quilted.
  • Expansion Period: Standard two-day period.
  • Warranty: 10-year non-prorated manufacturer’s warranty.

Material Composition

You will find that Sealy has given their all in making sure that this Posturepedic Optimum Radiance mattress will not be trapping any heat that could hinder your sleep.

While all 11 inches contain a certain form of cooling gel, there are some slight variances in each layer.

The first layer is the two inches of Opticool Gel Memory Foam, fused with the following two inches of OUTLAST Gold Gel Memory Foam. These two layers work together harmoniously to ensure that heat stands no chance while you sleep.

In case you were worried that all this cooling power means you’ll be lying down on a cold and inhospitable mattress, we can put your mind at ease. Thanks to the 7 inches of proprietary gel provided by OptiCore, you’ll find this mattress conforming to your body and offering support in all the places where it matters.

Since all layers contain memory foam, you will find that the mattress performs just as well as other memory foam beds, adjusting to the shape of your body and relieving any aches. This certainly explains the ‘posturepedic’ aspect of this mattress.

To finish things off as they should be, all foam layers have been infused with the Isofresh scent guard, which eliminates any odors that might be offensive.

This goes a long way in removing the factory smell from your new mattress and adds quite a while to your mattress’ expected lifespan.

Sealy Corporation: The Brand

Few companies can boast the rustic and respectable origin that Sealy Corporation has on the table.

What started with one simple farmer named Daniel Haynes stuffing mattresses with cotton in Texas to sell to his neighbors in 1881, ended up with a company that’s easily in the top three of mattress sellers on a global scale.

While the company has seen quite a bit of history ever since then, they still love their mattresses. These days, they operate from North Carolina and pour their all into finding the best ways to improve on their mattresses.

While a good night’s sleep is just as valuable as it was in 1881, Sealy has never once stopped finding new ways to make it happen.

Their Sealy Posturepedic Optimum Radiance mattress is the best Sealy mattress for anyone who finds themselves overly hot on a summer night.

Apart from that, they’re proud to say that it has nearly twice the expected lifespan of their earlier model, making it a great investment that shows care and dedication to their craft.

Stand Out Features

  • 10-Year Warranty: Sealy eases worries by offering a long ten-year warranty covering the cost of replacing your mattress due to manufacturing errors. Should you find a fault, contact customer service and they’ll deal with the issue from there! One less thing to fuss about.
  • Keeps You Cool: Warm nights and hot partners won’t be the reason you’re lacking in a good night’s sleep with the Sealy Optimum Radiance mattress. The gel layers keep you cool throughout the night, so you wake up refreshed instead of a sweaty mess.
  • Great for Couples: Thanks to the lack of motion transfer on this Sealy mattress, those who share a bed won’t have to worry about being bothered by their partner’s tosses and turning throughout the night, making for fewer yawns and arguments in the morning.

The Positives

Reduced Motion Transfer

If you share your bed with an active sleeper – or if you’re the one costing your companion some restless hours – then you know how much difference a good mattress can make.

Thanks to the different gel layers, this mattress has greatly reduced motion transfer, which makes it one of the best if you want to get through a night without being woken up when others get up for a glass of water.

This is great for partners with differing morning schedules, or for rowdy sleepers who share a bed – no one will have to worry about the other interrupting their sleep.

Locally Produced

We all want to do our bit for the environment and one great way of doing that is buying locally.

Sealy has their headquarters in North Carolina and 25 different production plants, each of them in the USA.

Ordering from local retailers means less of a carbon footprint caused by transportation, and supporting local products is always great as is. This helps to keep their prices down and our love for the environment up.

This also means getting ahold of Sealy won’t be a hard task since you won’t have to be connecting to representatives overseas during awkward hours, and also ensures for quicker shipping!

Long Lifespan

As mentioned, thanks to the continued efforts of the Sealy company, the Sealy Posturepedic Optimum Radiance mattress has almost twice the expected lifespan of their earlier models.

This kind of upgrade only spells good things for your wallet as well. A good mattress doesn’t just support you where necessary; it also lasts for a long time, so you don’t find yourself in the shop again two years down the road.

Don’t forget, you’ll also be covered by a warranty during the first ten years of owning this mattress.

Wake Up Refreshed

While it shouldn’t come as a surprise with the several layers of cooling gel, it wouldn’t be a Sealy Posturepedic review if we didn’t mention how refreshing this mattress is to sleep in.

Enjoy zero heat retention and bundle up for a night of sleep. This Sealy mattress will be a saving grace for those in warmer climates or those who tend to have a hotter body temperature while sleeping.

With this bed, waking up in a puddle of sweat, or tossing and turning trying to find the cool part of the mattress, will be a thing of the past.

The Negatives

Rather Firm

While ‘cushion firm’ results in the mattress being somewhere between plush and firm, some of our testers found this mattress to be more firm than this handle let on.

This is, of course, a matter of personal taste. Thanks to Sealy’s general return policy, it doesn’t hurt trying out what could very well be their best mattress, just to see how you like it yourself.


Those on a budget will not be thrilled by the price-tag on this Sealy mattress. While you definitely get what you pay for, some may not be looking to spend this amount of money on a mattress – at least not yet.

While this mattress doesn’t hit the top of the pricing scale and is quite the deal for obtaining a better night’s sleep, it can still be off-putting for someone looking for a real steal.

Overall Verdict

The Sealy Posturepedic Optimum Radiance is a mattress that came with a goal in mind and has certainly managed to fulfill it.

Thanks to the infusion of cooling gel in every part of this mattress, you’ll find that even the most tropical nights can’t raise a sweat.

The added scent reduces the factory odor and makes for a more pleasant time while you wait the necessary two days to let your mattress properly expand.

The memory foam layer performs as expected, providing support to any aching limbs and reducing motion transfer at the same time.

While it’s a great mattress, the Sealy Radiance does come with a caveat. Since size availability might be limited, you don’t have much leeway when you happen to own a different sized bed frame.

There is also only one firmness level, meaning that if you don’t like a mattress that’s harder than plush, you are out of luck.

Nonetheless, if you happen to enjoy a harder mattress, we don’t see any reason why you couldn’t have the sweetest of dreams on this particular Sealy model.
