Expert Review by Jed
The Twin XL Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress boasts a Comfort Scale rating of 1, perfectly designed for stomach sleepers and those who prefer an extremely firm sleeping experience. This mattress offers impressive comfort technology, including Beautyrest Gel Memory Foam, Firm Comfort Foam, a Beautyrest Pocketed Coil System, a Ventilated AirCool BeautyEdge, and an InfiniCool Surface.

The Twin XL Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress is fully-functional, affordable, and straightforward. The Ventilated AirCool BeautyEdge lines the mattress, making it easier to spread your wings without rolling off. Firm Comfort Foam completes the firm feel of the mattress, ensuring you get the sleeping experience you desire. The InfiniCool Surface uses cooling materials below the quilt, enhancing temperature regulation and using antimicrobial fibers to keep your mattress clean. To top it off, the Beautyrest Pocketed Coil System is tried-and-true, with each coil providing solid support.

Finally, Beautyrest Gel Memory Foam, a premium foam, contours to the curves of your body to reduce tossing and turning. With these materials combined, the Twin XL Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress is a smart addition to your home furniture collection. Whether you place the mattress in your bedroom, guest room, or the bedroom of a housemate, the benefits far outweigh the cost.

To sum up, the Twin XL Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress is worth consideration by stomach sleepers. However, I wouldn’t recommend it for side and back sleepers, who require a much softer sleeping surface. If you want a firm sleeping solution that will last for years to come, considering adding the Twin XL Simmons Beautyrest Platinum Phillipsburg III Extra Firm Mattress to your home today.

Comfortable firm mattress
I needed a firm mattress because of sciatica, and this mattress was definitely an improvement over my old cheapo memory foam mattress. Even though it's rated at extra firm, this mattress is still comfortable for me thanks to the foam top layers. Actually, I wish the mattress was a little more firm in the middle where my hip would lie.
