Expert Review by Jed
Do you need a firm mattress for your bedroom, guest room, or living space? Our Twin XL Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress is the perfect addition to your home furniture collection. This impressive mattress is perfectly designed for side and stomach sleepers alike and offers a unique blend of comfort technology, including Beautyrest Gel Memory Foam, a Beautyrest Pocketed Coil System, a Ventilated AirCool BeautyEdge, an InfiniCool Surface, and AirFeel Foam.
The Twin XL Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress is designed for anyone who wants ongoing comfort. The InfiniCool Surface enhances temperature regulation with technology that also resists odor-causing bacteria, mildew, and mold. AirFeel Foam reduces motion transfer and ensures solid support. The Beautyrest Pocketed Coil System utilizes hundreds of individually-pocketed coils to contour to your body while promoting spinal alignment.

The Ventilated AirCool BeautyEdge lines the mattress, allowing users to take full advantage without rolling off. Finally, Beautyrest Gel Memory Foam contours to your body while promoting REM sleep, thus reducing tossing and turning. These traits, when put together, make the Twin XL Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress a dependable, long-lasting addition to your home.

The Twin XL Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress is worth consideration by side and stomach sleepers. However, I wouldn’t recommend it for back sleepers, who typically require a soft sleeping surface. If you want a firm sleeping solution that will change the way you rest, consider adding the Twin XL Simmons Beautyrest Platinum Phillipsburg III Luxury Firm Mattress to home today.

Not as firm as expected.
It's not as firm as I expected. I can feel myself sinking down some when I lie down.

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.

The springs on the mattress squeak!
When I am tossing and turning in my sleep, the springs on the mattress squeak and I don't I am obese. I did not have this experience with my previous mattress which was about 10 years old!

Nice but I don't love it
I was hoping to love it like I loved my last mattress for the first 15 or so years I used it. Mainly I think it lacks a soft enough top layer. I like the firm support it gives, but it is more like lying on a board than I was hoping. I don't like a pillow top, so this seemed like the best option. I am keeping it. I will say that the price, the purchase experience and the delivery service were excellent.

Firmer than expected, but very comfortable
My husband and I ordered a new mattress to replace our 8-year-old one. This mattress was significantly firmer, but we have not found it to be uncomfortable. I have slept well, and I feel especially supported on my back. The movement isolation also seems to be better, and I am awakened less often by my husband's movements. In addition, I was very impressed with my experience purchasing from US-Mattress. E-mails were prompt and informative, delivery was actually early, and all products arrived in great condition just as ordered.
