Capitol Bedding Petoskey Extra Firm

The Petoskey Extra Firm

The Petoskey Extra Firm is the hardest bed we have in our stores.

Better For Stomach Sleepers

• While the feel of the Petoskey Extra Firm isn’t quiiite the hardest bed we’ve ever had, it is pretty darn close. This lends itself to be better for most stomach sleepers who don’t want to sag into the bed the wrong way all night long. While the quilting provides some level of conformity, those who predominantly sleep on their side may find it a tad hard on hips and shoulders.

Better Materials

• Capitol Bedding is famous for its use of only the highest density foams for all of their beds, and the Petoskey Extra Firm is no exception. All foams in this firm bed are 1.5lb density and above. You won’t find many brands that use this level of materials at any price range.

Better on an Adjustable Base

• The Bolsa spring unit on the Petoskey Extra Firm is fully adjustable compatible. Pair the mattress with the Sealy Ease 4.0 for the perfect combination of a firm, hard feel that won’t sink and back-conforming goodness of the adjustable base.

One of the hardest-feeling mattresses in the store, if you’re looking for the only beds stronger, check out Therapedic’s entire TheraLuxe HD line-up. The Petoskey Extra Firm is a harder bed than the HD’s, but internally the HD‘s use a stronger spring and evn higher density upholstery for even greater durability.

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.
