Carbon fibers are interwoven into the memory foam to provide comfort in two ways. First, they offer additional support for your neck and back. Second, they also help alleviate overheating by channeling away extra warmth.

The open-cell memory foam is also infused with Gel Active Max technology to further ensure that you remain cool throughout the night. The open cells promote increased airflow, helping usher away heat through extra ventilation.

Underneath the comfortable mattress top is a foundation of individually wrapped springs that provide the bulk of the support. These springs act independently of one another, which allows them to contour to your body. They’re also strong and durable, so you’re well-supported for a long time.

The mattress is designed so it’s compatible with any premium adjustable base. Select a new base that you like, or use one you already have.

With 10 years of non-prorated warranty protection, this mattress is built to provide supportive comfort for a full decade. Sleep easy, knowing you’ll be well supported both now and in the future.

If you want a mattress that offers the firmest possible support and has many premium features, this iteration of the iComfort Hybrid line has everything you’re looking for. The Serta iComfort CF2000 Quilted Firm Twin XL Mattress may be perfect for you.
