TEMPUR-ActiveBreeze Smart Bed Mattress Review

“The ActiveBreeze absorbs most movements, so you’ll notice little to no motion transfer when your partner moves in bed, and vice versa. This is an added bonus for couples who sleep hot.” – Jackson

The TEMPUR-ActiveBreeze Smart Bed Mattress significantly reduces the spread of vibrations that could otherwise interrupt sleep. This common characteristic of memory foam models makes them some of the best mattresses for couples.

With two layers of motion-absorbing memory foam, many vibrations never reach the TEMPUR-ActiveBreeze Smart Bed’s coil core. Those that do reach the core often don’t travel because the pocketed coils can compress independently of each other.

We analyzed the motion isolation with a vibration sensor, detecting minimal movement when we dropped a kettlebell on the opposite side of the bed. Team members also reported noticing little to no vibration when a testing partner changed positions on the mattress.

“Pressure relief is one of the ActiveBreeze’s main draws, especially if you’re a side sleeper or you weigh less than 130 pounds. The foam layers form a close cradle to soothe your sore spots and prevent new pressure points from forming.” – Danny

As is standard for the best memory foam mattresses, pressure relief is among the top strengths of the TEMPUR-ActiveBreeze Smart Bed. Its two layers of memory foam contour to a sleeper’s body, spreading out weight for more even pressure distribution. The pocketed coil core adds to the effect by dynamically adjusting to the sleeper’s body shape.

Additionally, the bed includes an adjustable base that allows more customized lumbar support and position options to further enhance pressure relief and postural support.

Our pressure mapping showed that the TEMPUR-ActiveBreeze Smart Bed redistributed pressure fairly evenly across our testers’ bodies. This resulted in subjective tester reports of little to no notable pressure accumulation, including when lying on their sides.

“Temperature control is the ActiveBreeze’s defining strength. The state-of-the-art heating and cooling technology does wonders, even though you may notice a bit of heat buildup in the foam from time to time.” – Brad

The TEMPUR-ActiveBreeze Smart Bed Mattress is designed as a cooling mattress. Its features intended to improve temperature regulation give it superior temperature control to many memory foam models we look at.

The mattress itself starts out with a cover engineered to wick away heat. Next, both layers of memory foam are ventilated to let air circulate. Air also flows through the pocketed coil core, allowing heat to dissipate.

To further enhance the temperature regulation, the bed comes with an adjustable base with built-in fans. Three levels of temperature control are available, and partners can select separate levels for a more personalized experience.

Team members noted that they remained at a neutral temperature on the TEMPUR-ActiveBreeze Smart Bed Mattress. However, we recorded mild lingering heat retention with our laser thermometer and thermal camera.

“The coils provide some pushback, but the ActiveBreeze does buckle a bit when you sleep or sit along its edges. Feelings of roll-off may occur as a result.” – Danny

The TEMPUR-ActiveBreeze Smart Bed Mattress’ level of edge support is on par with many hybrid models. While it doesn’t have dedicated edge reinforcement, the coils in the core move independently to provide full-surface support. With a stable edge, sleepers can often use more of the mattress surface comfortably and sit along the perimeter more securely.

While our testers over 230 pounds noted a bit more edge compression, all of our team members were able to lie and sit along the perimeter of the bed without feeling like they might slide off.

“I didn’t struggle too much moving on the ActiveBreeze – there’s some nice pushback from the coils – but noticed some sinkage when changing sleep positions. This problem may be compounded for people who weigh more than 230 pounds.” – Jackson

Ease of movement isn’t the TEMPUR-ActiveBreeze Smart Bed Mattress’ strongest area, but it outshines many competing models that use memory foam. Since memory foam hugs closely and regains its shape fairly slowly, body impressions may linger and impede movement. However, the TEMPUR-ActiveBreeze Smart Bed’s pocketed coil core is sufficiently responsive and supportive to prevent the “trapped in the bed” sensation sometimes associated with memory foam.

All of our testers changed positions relatively easily on the mattress, but those over 230 pounds needed to put in slightly more effort since they sank in more deeply.

“Off-gassing odor for the ActiveBreeze was strongest for the first few hours after we unboxed the mattress. The smells linger a bit, but should completely clear out within two days.” – Brad

Like any mattress with synthetic foam, the TEMPUR-ActiveBreeze Smart Bed may have an initial odor left over from manufacturing. Off-gassing occurs when volatile organic compounds (VOCs) created during foam production linger in the material. You may experience this as a “new mattress” smell.

While VOCs aren’t typically seen as harmful, some sleepers dislike their odor. Ventilating the bedroom can help dissipate the smell more quickly.

Our team members noticed a mild to moderate initial odor when the TEMPUR-ActiveBreeze Smart Bed arrived in our sleep lab, but they observed little to no odor the next day.
