Expert Review by JedIf 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.

Not what I expected but all worked out.
I had ordered this same mattress 2 years ago for my rental in Virginia. Loved it so I ordered it for our home in Florida. It was definitely much more like an extra firm than what was expected. I was pleased that US Mattress worked with me to get a replacement after Trying to get it to workout after 90 days.

U.S. Mattress meets challenges in the time of COVID-19
The Simmons Beautyrest Spring Grove mattresses are excellent. U.S. Matress sales people and customer service were a pleasure to deal with. There was understandable issues of delivery and setup due to the COVID-19 pandemic, but U.S. Mattress was able to work these out in partnership with XPO logistics. Thank you, U.S. Mattress.

Very good choice
Solid quality. This mattress provides good support without being too firm. We've had it for about 6 weeks and are very satisfied with the purchase.

Good mattress overall
I like this mattress but if I were to buy it again I would buy the plush model. I like a firm mattress and this is not quite as firm as I had expected. It has developed a slight indentation where I sleep. I have some lower back problems and this mattress has really helped. I added a 1 inch thick memory foam layer and now it's really comfortable

Great Mattress
Great mattress! I had a serious spinal injury and several surgeries to my lower back and for the first time in two years I've slept through the night and am waking up without the usual crippling pain I experienced with our old mattress. I'd highly recommend this for folks with lower back issues who sleep on their side.

Excellent quality and service
The mattress is just the right firmness and it is extremely comfortable. And the guys who installed it were very professional and worked very quickly, I think it took them only 15 minutes!

It seems like a pretty good quality mattress I have put it on the floor with the foundation Under it .when it was on the frame that I bought it developed unsupported areas would highly recommend just putting mattress on a platform by itself not spending the money on a foundation. Frame is worthless in my opinion

Flawless
Great experience.
Delivery and take away was a snap. We got what we ordered and it was a new stock item.... meaning the date stamp was one month prior to delivery. Flawless trsnsaction.
