What is Serene® Foam?
Responsive Support: Unlike conventional memory foam that can feel slow to react, Serene® foam adapts quickly to your body’s contours. This immediate responsiveness means optimal pressure relief and precise support, whether you’re shifting positions or settling in for the night.
Enhanced Breathability: Traditional memory foam is notorious for retaining heat through lack of airflow, which can disrupt your sleep. Serene® foam is engineered with advanced open-cell technology to promote superior airflow, keeping your sleep surface cooler and more comfortable throughout the night.
Long-Lasting Durability: The Hadley’s Serene® foam is built to maintain its supportive properties over time. Its resilient nature ensures that your mattress stays consistently comfortable, providing enduring performance without the sagging or wear typical of standard memory foam.
Dynamic Motion Management: Thanks to its rapid recovery capabilities, Serene® foam minimizes motion transfer – while making it easier to roll around and move on the mattress surface. This means you and your partner can enjoy uninterrupted sleep, even if one of you moves during the night.
Great for All-Over
The Hadley is designed with a combination of high-density upholstery (Serene® Foam) in the quilting, providing a luxuriously soft and conforming feel that side sleepers will find irresistible. The firmer foams underneath ensure you won’t sink too far, while having enough conformity on the top to suit all types of sleepers.
Compatible with Adjustable Bases
The Hadley is designed to work seamlessly on all adjustable bases. Pair this mattress with the Sealy Ease 4.0 or Rize Clarity II to create the ultimate sleep setup that combines plush, conforming comfort with the personalized support of an adjustable base.

The Capitol Bedding Difference
For more than 50 years, Capitol Bedding has been crafting high-quality mattresses with a clear focus: durable, comfortable sleep that stands the test of time. Long before “no-flip” mattresses became the norm, Capitol committed to building one-sided designs using truly premium materials—especially high-density foams engineered to keep their feel and support for years, not just months.
That commitment led to the use of foams like P2536 (2.5 lb density, 36 ILD), P2560 (2.5 lb, 60 ILD), and P2426 (2.4 lb, 26 ILD), each chosen for a specific role in comfort and support. Instead of relying on the 1.0–1.5 lb foams commonly found in many mass-market mattresses, Capitol builds with 1.8 lb, 2.4 lb, and 2.5 lb foams that are designed to break down far more slowly and maintain their original feel much longer.
Key Benefits of Capitol’s High-Density Foam
High-Density Foam = Longer Life Higher-density foams hold their shape and support significantly better over time than standard low-density foams, helping the mattress feel “new” for more years.
Purpose-Built Foam Types
P2536 (2.5 lb, 36 ILD): Focused on durability and everyday support.
P2560 (2.5 lb, 60 ILD): Firmer, more supportive feel for heavier use and stronger lumbar support.
P2426 (2.4 lb, 26 ILD): Softer, more cushioning comfort where pressure relief is needed.
Proven Firmness Retention Over a 10-year span, Capitol’s typical foam choices retain firmness far better than commodity foams:
2.5 lb foam: about 8% firmness loss
2.4 lb foam: about 9% firmness loss
1.8 lb foam: about 20% firmness loss Compare that to lower-density foams often used elsewhere:
1.2 lb foam: about 38% firmness loss
1.0 lb foam: about 42% firmness loss
Premium, U.S.-Made Materials Capitol sources its foams from Future Foam, a leading family-owned U.S. producer of Flexible Polyurethane Foams (FPF), chosen for consistent quality, performance, and longevity.
While these premium materials cost more to build with, Capitol Bedding believes that better foam makes better mattresses—and better mattresses make for better sleep. The result is a line of products designed to feel supportive and comfortable for years, not just in the showroom, giving you a bed that truly earns its place in your home.
