Expert Review by Jed
Do you need a firm mattress for your bedroom, guest room, or living space? Our King Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress is the perfect addition to your home furniture collection. This impressive mattress is perfectly designed for stomach sleepers and those who prefer an extremely firm sleeping experience. It offers a unique blend of comfort technology, including Beautyrest Gel Memory Foam, Firm Comfort Foam, a Beautyrest Pocketed Coil System, a Ventilated AirCool BeautyEdge, and an InfiniCool Surface.
The King Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress is designed for anyone who wants ongoing comfort. Beautyrest Gel Memory Foam, a premium foam, contours to the curves of your body to reduce tossing and turning. The Beautyrest Pocketed Coil System is tried-and-true, with each coil providing solid support. The InfiniCool Surface uses cooling materials below the quilt, enhancing temperature regulation and using antimicrobial fibers to keep your mattress clean.

Firm Comfort Foam completes the firm feel of the mattress, ensuring you get the sleeping experience you desire. Finally, the Ventilated AirCool BeautyEdge lines the mattress, making it easier to spread your wings without rolling off. These traits, when put together, make the King Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress a dependable, long-lasting addition to your home.

The King Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress is worth consideration by stomach sleepers. However, it is not recommended for side and back sleepers, who require a much softer sleeping solution. If you want a firm sleeping solution that will change the way you rest, consider adding the King Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress to home today.

Long time back pain and knee pain gone
A little firmer than expected (under the impression that the firmness rating is always an overestimation; was expecting more like a 2-2.5), but this is exactly what I needed. The firmness rating is as advertised as "1". Of course it is not as comfortable as other plush beds on first touch, but after 3 weeks of use, my long time back pain is not an issue anymore. Long time knee pain (runners knee) has also been bothering for quite some time despite numerous sessions of physical therapy. This is also unexpectedly resolved. Will see how durable this bed is, but for now - highly recommended!

Firmest mattress I have ever owned.
I was wary as previous mattress purchases have claimed to be very hard but were soft around the edges or in the middle. This mattress is the hardest I have seen or owned. I am sure it is not for everyone but is perfect for me.

Great customer service and price match
They did a great job with delivery and removal of the mattress. They also price matched their own add. It took 2 calls to get it put through but they did a great job after the second call.
