Pro Breeze Medium Hybrid too Hot

Mattress Talk General Mattresses Questions
1

Before knowing of The Mattress Underground, two years ago I purchased a Pro Breeze Medium Hybrid mattress and adjustable base.

Unfortunately, it’s too hot while sleeping with my girlfriend. We’ve taken measures like buying a breathable mattress protector, Land End percale sheets, and a Lands End lightweight cotton quilt. We also keep the temperature at 64 during the night. The mattress starts off cool, but the foam captures the heat and makes the temperature uncomfortable through the night.

It seems like the adjustable base is solid and not breathable. Would something like a coconut mattress pad be helpful? Are there any other ways to make the bed more breathable and cooler?

Hi Jpeterham,
Welcome to the community.

You’re already doing a lot of the right things to sleep cooler, but you’re correct that the issue may stem from a combination of the Pro Breeze’s foam layers (which tend to trap heat despite Tempur-Pedic’s cooling claims) and the fact that your solid adjustable base, which one might suggest restricts airflow underneath the mattress, it is really of no consequence as a solid base is better for your mattress and support.

The bottom line is the mattress, period. The breathable accessories are very good when you have a natural fiber or latex mattress, they help maintain that positive breathable flow.

You do have a couple of options, some more budget friendly than others. The Perfectly Snug Smart Topper is at the higher end of the budget spectrum. I reviewed mine here and here.

The key to staying cool while you sleep is to prevent the heat your body gives off from being trapped and reflected back at you. Traditional memory foam mattresses, like those made with Tempur material, tend to retain heat, so instead of dissipating, the warmth gets redirected right back to you. It can feel like you’re sleeping on a heating pad or even hot coals, as the heat rises and lingers.

If you’re serious about staying cool, the best, though expensive, option is a mattress topper made with horsehair, or combinations like horsehair and wool, or horsehair and cotton. These natural materials are extremely breathable and allow heat to dissipate efficiently. A slightly less expensive, but still premium, alternative is a 3" organic wool topper. Talalay latex toppers can also help, as they retain less heat than memory foam, though they still hold some warmth. As a last resort, consider highly breathable options like a Monze or airfiber-style topper, which allow air to flow freely through and out the sides, especially when paired with low thread-count cotton sheets.

The bottom line is, the more distance you can put between yourself and memory foam, the cooler you’ll sleep. That said, some memory foam mattresses, like those from @Tempflow, do things differently. They still use Tempur-style foam, sometimes even the original high-density 5lb+ type, but they integrate a patented airflow chamber system designed to help heat escape.

Now, when you look at Tempur-Pedic’s own claims, especially on their “Breeze” line, it’s worth reading the fine print. They claim the LuxeBreeze® sleeps “up to 10 degrees cooler,” but here’s the full context:

++ LuxeBreeze® feels up to 10 degrees cooler based on the average heat index increase of TEMPUR-LuxeBreeze® compared to TEMPUR-ProAdapt® models measured over an 8-hour period. ProBreeze® feels up to 5 degrees cooler based on the average heat index increase of TEMPUR-ProBreeze® compared to TEMPUR-ProAdapt® models measured over an 8-hour period.

So technically, they’re not lying, but in my opinion, the marketing is a bit misleading.

I wish I had more positive news, but I hope this gives you some helpful direction.

All the best,

Maverick

Hi Maverick,

Thank you for the quality response! I really appreciate you taking the time to provide such detailed information.

To confirm my understanding, it sounds like the best option for cooling, in order, is a horse hair topper, followed by the Perfectly Snug Smart Topper, then a wool topper, then a Talalay latex topper, and finally a Monze or airfiber-style topper. Is that correct?

An environmental allergy test from last summer coincidentally showed I’m pretty allergic to horses. I’m not sure if this pertains to horse hair or dander, but this allergy makes me hesitate to choose a horse hair topper.

I’m currently researching the Perfectly Snug Topper and a 3-inch wool topper, possibly the Wolly Topper from Woolroom. Disregarding price, would you recommend one over the other?

My hope is that one of these toppers will extend the lifespan of our current Tempurpedic mattress for a few more years. After some reading on MattressUnderground, I plan to consider one of the recommended mattresses when we eventually need a new one.

Thank you again for your help!

Hi Jpeterham,

In terms of ranking based on cooling performance, you’re close. Remember, there are things actively cool, like the Perfectly Snug Smart Topper, Chill Pad, Eight Pods, Bed Jet, and so on have active cooling. There there are the thermo-regulators.

  1. Horsehair – Best for passive airflow and zero heat retention. It’s a natural thermoregulator, but as you mentioned, allergies could be a real concern. Even if it’s just the dander you’re allergic to, it’s worth confirming with your allergist before choosing this route.
  2. Perfectly Snug Smart Topper – Offers active cooling, which can be more effective in hot environments or for hot sleepers. It doesn’t just stay cool, it makes you cool.
  3. Camel Hair & Wool – Both are excellent thermoregulators. Wool (like the Wooly Topper) is widely used, supportive, and naturally breathable. Camel hair is rarer but has similar properties with slightly different feel and loft.
  4. Talalay Latex – Breathable and responsive, with good airflow through the material. Great for support, though it retains a bit more heat than wool or horsehair.
  5. Airfiber/Monze-style toppers – Offer airflow through open structure but may not regulate body heat as well as natural fibers or active cooling tech.

Between the Perfectly Snug and the Wooly Topper, here is how you should position each:

If active cooling and tech features (like dual-zone temperature control) matter to you, and you’re looking for a cooler sleep experience especially during warmer months, then the Perfectly Snug is a strong choice.

If you prefer natural materials, are sensitive to Electro Magnetic Fields or prefer something lower-maintenance, the Wooly Topper is fantastic. It’s also better at providing a plush, pressure-relieving buffer on top of a firmer mattress like the Tempurpedic.

Since your goal is to extend the life of your Tempurpedic while improving comfort, either topper can work, just depends whether you’re leaning toward a tech-enhanced cool or a natural thermoregulating feel.

As far as horsehair and allergies.

Horse allergies are most often reactions to proteins found in horse dander, saliva, and urine, not the hair itself.

However, horsehair can still contain trace proteins that could remain even after cleaning, boiling, and processing, especially if the purification process isn’t extensive enough to denature or remove all allergenic proteins.

Boiling, braiding, and cleaning do significantly reduce allergens, and high-end manufacturers often sanitize horsehair thoroughly. But even so, there’s no absolute guarantee the final product is allergen-free. But most folks, even those with allergies will not have ill effects.

Additionally, allergies vary by individual. Some people react only to airborne dander; others might react to residual proteins even in well-processed materials. The same is true for camel hair. Natural camel hair has keratin based protein fibers, camel hair retain dust which can attract dust mites, which folks can react to, unless housed in dust resistant covers.

Hope that helps clarify! Happy to help further as you decide.

Maverick
