Know before you buy
The plush pillowtop provides a soft, cloud-like surface that contours closely to your body, offering a more cushioned feel than a traditional firm mattress. It is designed for those who prefer a luxurious, sink-in sensation while still receiving deep-down support from the coil layers.
Diamond particles are highly conductive, meaning they help draw heat away from your body and dissipate it throughout the mattress. This, combined with the ventilated latex layer, promotes consistent airflow to keep you cooler throughout the night.
No, this mattress is specifically engineered for superior motion separation. The combination of Triple-Stranded Pocketed Coil Technology and 2K Nano Coils works to isolate movement, ensuring that motion on one side of the bed is not transferred to the other.
The included RTG Sleep 2900 base allows you to elevate the head of the mattress, which can be helpful for reading, watching TV, or alleviating snoring and acid reflux. It provides a customized sleep experience that a standard flat foundation cannot offer.
Yes, all foams used in the Beautyrest Black Series Three are CertiPUR-US certified. This means they are made without ozone depleters, mercury, lead, or other heavy metals and have low VOC emissions for better indoor air quality.
The mattress is 16.75 inches thick. Because of this profile, you will definitely need deep-pocket or extra-deep-pocket fitted sheets to ensure they stay securely in place.
