Capitol Bedding Suttons Bay Cushion Firm
A deceptively firm Capitol mattress with strong value
The Suttons Bay Cushion Firm is one of the best firm values on the floor, but it needs to be described clearly: it has been come to known as a “deceptively firm”. The word “cushion” can make shoppers expect something softer than it really is.
For the right customer, that firmness is the reason to buy it. This is a mattress for people who want a flatter, steadier surface with just enough give at the top to keep the bed from feeling completely bare.
Comfort and feel
The Suttons Bay Cushion Firm has a cushion-firm feel, but it leans firm. It feels steadier and less plush than many customers expect.
It is not a soft mattress. It is better described as firm with just a bit of surface comfort.

Our take
The Suttons Bay Cushion Firm is a very useful mattress because it does not pretend to be something it is not. It is firm, locally made, and priced well. For the right person, that combination is hard to beat.
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.
