Beautyrest is a heritage brand created by Simmons Bedding Co. in the 1920s. Now owned by Serta Simmons Bedding, Beautyrest offers several lines of hybrid mattresses to address a sleeper’s various needs and preferences. We’ve previously reviewed the more affordable Beautyrest Level Two Hybrid, as well as the luxurious Beautyrest Black Hybrid Series One line.
This review focuses on the Beautyrest Black Hybrid Series Three XCS Mattresses. We brought these mattresses into our Test Lab to measure their performance in terms of pressure relief, motion isolation, temperature regulation, and overall support. We also had our testing team members take the mattresses home to try them in real-world settings. Read on to see what we found, and to identify if the Beautyrest Black Hybrid Series Three XCS could be the mattress for you.

Answer a few questions to find the right mattress for your unique needs
Testing Team Takeaways
To test the Beautyrest Black Hybrid Series Three XCS Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.

“The Firm Black Hybrid Series Three XCS felt comfortable to me, and I slept well on it. But, it felt a little too stiff whenever I rolled onto my side.”

“I really enjoyed trying out the Plush model of the Series Three XCS. It relieved my pressure well and I never noticed motion transfer from the other side of the bed. “

“The Medium model of this mattress felt immensely comfortable to me as a side sleeper, but when my weighted blanket was on, I did feel some heat collecting beneath me.”
Sleeping Style and Body Weight
Side Sleepers
Most side sleepers find the Beautyrest Black Hybrid Series Three XCS comfortable. The Medium mode promotes even alignment for side sleepers, allowing the heavier areas of their body to sink into the memory foam a bit, but not too far. The mix of memory foam and polyfoam in the comfort layers excels at relieving pressure, which is an important feature for side sleepers who feel pressure points around their hips and shoulders.
Because the Medium works well for side sleepers of all body weights, this mattress model is attractive to sleepers who share a bed with a partner who sleeps in a different position or has a different body weight. That said, side sleepers weighing less than 130 pounds can find even more comfort on the Plush model, and those over 230 pounds may prefer the Firm model’s extra support.
Back Sleepers
The Firm model of the Series Three XCS provides a comfortable sleeping surface for nearly all back sleepers across different body weights. However, back sleepers may also find comfort on the Medium, and those under 130 pounds might even prefer the Plush design. This range of options makes the mattress a good choice for back sleepers who share a bed with a partner who is a different body weight or prefers a different sleep position.
The Beautyrest Black Hybrid Series Three XCS works well for back sleepers because of its targeted support beneath the lower back. While softer memory foam contours to the upper body, polyfoam and pocketed coil layers keep the hips from sinking into the mattress too deeply. When hips sink into the mattress too deeply, the lower back can become strained and sore.
Stomach Sleepers
For stomach sleepers weighing 130 pounds or more, the Firm Series Three XCS model is supportive enough to prevent their midsections from sinking in and interfering with spinal alignment. Most stomach sleepers in this weight range won’t find adequate comfort and support on the Plush and Medium models.
Stomach sleepers under 130 pounds should find adequate support on any firmness level of this mattress, including the Plush and Medium. On the other hand, stomach sleepers over 230 pounds may want to opt for a different mattress altogether. While the Series Three XCS Firm model can provide average comfort to them, it may not be as comfortable as thinner, more supportive mattresses that contain less foam padding.
Mattress Performance
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.

Memory foam sewn to the cover is infused with cooling phase change material, which allows you to enjoy deep contouring and cushioning without too much heat retention.
The comfort system contains five more layers of memory foam and polyfoam. At least two of these layers are composed of ventilated foam, which is hole-punched to promote airflow near the surface.
The support core consists of pocketed coils over high-density base foam. Polyfoam rails surround the edges of the coil layer to boost perimeter support.

All models have a 14.5 inch profile. Due to this height, you may need to invest in a deep-pocket fitted sheet.
Since the Beautyrest Black Hybrid Series Three XCS mattresses are heavy, especially in larger sizes, we recommend lifting and moving your bed with at least one other person.
