Expert Review by Jed
If your home doesn’t have a mattress that meets your needs, what’s the point in sleeping? For a firm mattress with quality to spare, consider the King Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress. This impressive mattress boasts Beautyrest Gel Memory Foam, a Beautyrest Pocketed Coil System, a Ventilated AirCool BeautyEdge, an InfiniCool Surface, and AirFeel Foam. It also offers a Comfort Scale rating of 3.5, making it ideal for side and stomach sleepers alike.

The King Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress is a quality addition to any bedroom, guest room, or living space. Beautyrest Gel Memory Foam contours to your body while promoting REM sleep, thus reducing tossing and turning. The Ventilated AirCool BeautyEdge lines the mattress, allowing users to take full advantage without rolling off. The Beautyrest Pocketed Coil System utilizes hundreds of individually-pocketed coils to contour to your body while promoting spinal alignment.

AirFeel Foam reduces motion transfer and ensures solid support. Finally, the InfiniCool Surface enhances temperature regulation with technology that also resists odor-causing bacteria, mildew, and mold. When these materials are fused together, magic happens. The King Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress is everything you need in a mattress and more.

In conclusion, the King Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress should be seriously considered by side and stomach sleepers. I wouldn’t recommend it for back sleepers and those who prefer a softer sleeping experience. If you need a firm mattress that will continue to impress, consider adding the King Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress to your home furniture collection today.

Good purchase
We had this mattress for a few months now. My wife and I love this mattress. The firmness is as described. Very comfortable for side sleepers.

So far so good. A firm but very comfortable mattress, where the top has a softness that gives support, but the whole mattress is sturdy and is very stable.

Great Mattress!
Great mattress!! Firm but soft. No low back aches which I've had with too soft mattresses. Ideal to put a 2" or 3" latex foam on top to give it a plush feeling like a hotel bed. Much better than using memory foam topper which degrades and are made of nasty stuff.

Absolutely awesome!
I am getting a superb quality of sleep every single night since receiving my mattress and 3” latex Talalay topper. As a side sleeper, my old mattress caused me discomfort on both my hip and legs. This no longer happens. I bought the mattress to mimic the comfortable sleep I had experienced at a particular hotel. Actually, my new mattress is even BETTER! I am thrilled.

Too firm for given rating
This mattress is much firmer than advertised. I’ve ordered other mattresses (4) from the same service with similar and same ratings for firmness and plushness. This one is extra firm and unforgiving for someone in the 130 to 160 pound category. It hurts my back. It’s even a bit too firm for my husband who’s 6’3” about 230 pounds.
