Beautyrest Harmony Luxe Mattress

Simmons Beautyrest Harmony Lux Carbon Medium

Rather than focusing on one area in particular the Beautyrest Harmony Lux Carbon mattresses feature the most recent developments in comfort, support and cooling that all work together in a perfect harmony for a perfect night’s sleep. Beautyrest’s Precision Support System utilizes T2 Pocketed Coil technology to provide the kind of support that is especially important for those with medical complications requiring lumbar or back support due to the additional support in the lower-back areas, more specifically in the center third of the mattress. Seaqual and Infinicool have both partnered together with Beautyrest to create an innovative new fabric technology that uses recycled plastic gathered from our oceans. This environmentally conscious but durable and luxurious new fabric provides and much cooler sleeping experience. Beautyrest Gel Memory Foam and RightTemp Wave Foam sits on top of the pocketed coils to provide unrivaled pressure relief and cooling. RightTemp Wave Foam is engineered with conductive materials that are designed to pull excess heat away from the body. Don’t settle for less and go with Beautyrest’s best. Beautyrest Harmony Lux Carbon series mattresses are highly rated and on Beautyrest’s website 91% of customers who rated their mattresses online rated it 5 stars with the remaining 9% giving 4 of 5 stars. This particular model is Medium and rates an 8 of 10 on the Comfort Scale with 1 being very plush or soft and 10 being the firmest.
