Capitol Bedding Northern Nights Firm Hybrid

Great for All-Over

The Northern Nights Firm is designed with high-density Serene® Foam as the primary upholstery layer, 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.

High-Quality Materials

Capitol Bedding is committed to using only the finest materials in their mattresses, and the Northern Nights Firm Hybrid is no exception. This plush bed features premium, high-density foam materials of 1.8lb density and above that not only deliver a luxurious sleeping experience but also ensure long-lasting durability and support.

Compatible with Adjustable Bases

The Northern Nights, designed to offer a slightly firmer feel, works seamlessly with adjustable bases. Pair this mattress with the Sealy Ease 3.0 or Tempur ERGO to create the ultimate sleep setup that combines plush, conforming comfort with the personalized support of an adjustable base.

Transform your nights with the Northern Lights, and indulge in the sumptuous comfort tailored for you by one of Michigan’s top manufacturers.

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.
