Are Sealy’s Cooling Features and Posturepedic® Tech Worth the Price?
Sealy Posturepedic Optimum Chill Trio Dione is a cooling gel memory foam mattress. It’s produced by Sealy, a well-known American bedding company.
Chill Trio Dione incorporates Sealy’s Posturepedic® technology, which provides targeted body support. The mattress has a layer of cooling gel memory foam. Its top cover features Sealy Chill™ 2.0 cooling yarn to help absorb and dissipate heat.
It’s true that the Chill Trio Dione offers a couple of enticing cooling features. But this Sealy mattress contains only two foam layers and costs a staggering $3,299 for a queen size.
Chill Trio Dione comes with a 100-night sleep trial. However, if you decide to return it, you can only exchange the mattress. You will also have to pay a $65 exchange fee to cover new mattress delivery and old mattress pickup. You will have to pay the difference if you want to exchange for a more expensive mattress. If you choose a cheaper replacement, you only receive in-store credit rather than a refund.
If you’re looking for a cooling mattress with zoned support, Octave may be a better choice. This Canadian mattress offers even more cooling features at a fraction of the price: just $899 for a queen. Octave also offers a more competitive 365-night trial. This includes free mattress pickup and a full refund should you want to return your mattress.

First Impressions: Straight Out of the Box
The Arrival
Sealy Posturepedic Optimum Chill Trio Dione can be purchased from Sleep Country Canada either online or in person at one of their stores. Sleep Country offers free shipping on orders above $75, so mattress deliveries are free by default. Chill Trio Dione ships wrapped in plastic.
The mattress arrives within 3–5 business days via Sleep Country’s own delivery teams. Customers may opt for either a simple delivery or pay to upgrade to Sleep Country’s Green Glove Delivery. This service includes delivery to the room of the customer’s choice, setup, removal of the customer’s previous mattress, and disposal of used packing material.
The Unboxing
The mattress is relatively easy to unpack. The plastic sheet isn’t difficult to remove, though two people are needed to haul the mattress to its desired room and position.
The Look
Sealy Posturepedic Optimum Chill Trio Dione has a soft, icy-looking colour scheme. It features an irregular white-and-grey pattern with light blue highlights. A blue band encircles the mattress halfway up, with Sealy’s brand and model logos at the corner.
The Feel
Sealy Posturepedic Optimum Chill Trio Dione has a medium-firm feel. It feels slightly cool when you first lie down, due to Sealy’s OptiSense™ Liquid Gel Memory Foam with ChillActive™ technology. Despite the relative firmness, this mattress has a fair bit of “hug” to it. You will notice your body sinking into the mattress’s surface.
Official Test Results: How Do Engineers Rate Sealy Posturepedic Optimum Chill Trio Dione?
The following results were determined by licensed 3rd-party engineers, commissioned by us:
To be able to accurately rate and compare the performance of the mattresses reviewed on this website, it was necessary to hire licensed 3rd-party engineers. Their independence and operating standards help to ensure the results remain unbiased, valid, and reliable. Each mattress was evaluated using the same strict methodology to protect the overall integrity of the results. The full report is linked below and has been given the official stamp of approval from a certified engineer operating under a strict ethical code of conduct.
*Be advised: Mattress testing conducted outside of this professional standard poses a greater risk of validity errors or reviewer bias.*
How Our Engineers Test Each Mattress:
| Test Scores | Chill Trio Dione |
|---|---|
| Firmness: | 6.2 / 10 |
| Edge support: | 8.5 / 10 |
| Motion isolation: | 7.1 / 10 |
| Bounce: | 2.9 / 10 |
Feel & Firmness
The Sealy Posturepedic Optimum Chill Trio Dione is a medium-firm mattress. According to the testing conducted by third-party engineers (commissioned by us), it is rated at 6.2 / 10 on the firmness scale, and has a fair amount of ‘hug’ when lying down.
Medium-firm mattresses are a good choice for most Canadian sleepers as they tend to suit the widest range of body types and sleep styles.
Edge Support
Foam mattresses often don’t have good edge support. For mattress shoppers considering switching from an innerspring mattress to foam, this lack of support when sitting or sleeping near the edge of the bed can be a concern.
However, Chill Trio Dione scores surprisingly well for edge support at 8.5/10. This adds to the mattress’s overall support and stability.
Motion Isolation
Motion isolation in foam mattresses is usually very good. This is one of the main reasons why some couples make the switch from innerspring to all-foam.
According to the testing conducted by third-party engineers (commissioned by us), Chill Trio Dione scored 7.1 / 10 on the motion isolation scale. This is a good score, although it doesn’t stand out from other foam mattresses tested on this site.
Bounce
Foam mattresses tend to provide good motion isolation, which usually translates to a lower bounce rating.
According to the testing conducted by third-party engineers (commissioned by us), Chill Trio Dione’s bounce score is 2.9 / 10. This is low, even for a foam mattress. You may experience difficulty rolling over or changing positions while lying down.
Mattress Construction: What’s Chilll Trio Dione Made Of?
| Construction | Chill Trio Dione |
|---|---|
| Mattress height: | 11" |
| Number of layers: | 2 |
| Comfort layers: | 3" Memory foam |
| Support layer: | 8" Support foam |
| Cover materials: | Sealy Chill™ 2.0 cooling yarn |
| Machine washable: | No |
| Made in: | Canada |
Sealy Posturepedic Optimum Chill Trio Dione is available in one medium-firm option only. It is promoted as a cooling mattress, but it only has a few cooling features for a mattress with such a premium price.
Chill Trio Dione Mattress Layers
This Sealy Posturepedic Optimum Chill Trio Dione mattress contains only two foam layers: a comfort layer and a support layer. Most other memory foam mattresses also include at least one transition layer. This makes Chill Trio Dione highly unusual for a foam mattress, especially at its high price point.
- First layer: 3″ of memory foam. This layer provides comfort and conforms to your body the most as you sleep. Foam density: unspecified.
- Second layer: 8” of support foam. This dense layer is the mattress’s foundation and prevents you from sinking too far into the mattress while you’re sleeping. Foam density: unspecified.
Sealy hasn’t disclosed the exact composition of its foam layers. Sleep Country Canada’s website claims that the foam layers use OptiSense™ Liquid Gel Memory Foam with ChillActive™ technology to help conform to your body and cool you as you sleep. No information is available on where and in what proportion these product features are used.
All foam used in Chill Trio Dione is CertiPur-US® certified.
Chill Trio Dione Mattress Cover
The mattress cover features 2x Sealy Chill™ 2.0 cooling yarns. This yarn is meant to contribute to heat dissipation, but how it does so is unknown. The exact composition of the Ultra-stretch Chill-Trio™ is unspecified on either Sealy’s or Sleep Country Canada’s websites.

Sealy’s involvement in the mattress industry goes back to the 1880s, with the company taking its name from the Texas town where it first began producing made-to-order mattresses. The business grew rapidly and became an industry leader by the 1920s, contributing to many innovations and patents. The Posturepedic line was launched in the early 1950s to “provide technology that delivers deep, targeted support right where you need it.” The large company also owns Stearns & Foster, another well-known mattress brand.

Final Thoughts on Sealy Posturepedic Optimum Chill Trio Dione
Sealy is a well-established name in the mattress industry, and the Posturepedic® line has been around for a long time. However, at $3,299 for a queen-size, Chill Trio Dione falls short in terms of value due to the mattress’s high price, low number of layers, limited features, and restrictive policies around returns and exchanges.
Instead, try a memory foam mattress with more cooling features from competitors like Octave. Octave costs significantly less ($899 for a queen) and offers far more value for the price. It comes with cool-to-the-touch CryoFusion™ cooling nanofibre cover, heat-dissipating CopperGel™ memory foam, and temperature-balancing PolarMAX® phase-change material. Because of its excellent value and advanced cooling, Octave is Mattress Reviews’ Top Pick for Best Cooling Mattress.
