Capitol Bedding Brooklin Hybrid

Overview

The Brooklin Hybrid is designed to feel like a “nice, grown-up hybrid” without getting into ultra-thick, ultra-soft territory. The top uses Capitol’s Sustain® Comfort Foam for plush, contouring support, backed up by a responsive latex-infused layer and a Quantum Edge® wrapped coil system. The result is a medium-plush, supportive feel that works for a wide range of sleepers, wrapped in a REPREVE® cover that turns recycled plastic bottles and fabric waste into a soft, breathable fabric.

Feel & best for

• Overall feel: medium-plush — cushioned on top with a clearly supportive coil core.

• Best for: side and combination sleepers who want pressure relief at shoulders and hips without feeling swallowed by the mattress.

• Also works for: back sleepers who like a bit more give on top but still want real underlying support.

• Not ideal for: customers who want an ultra-firm surface or the softest, deepest pillowtop in the store.

Key construction & materials

• REPREVE® cover made from recycled plastic bottles, fabric/yarn waste, and ocean-bound plastic, creating a soft, breathable top while reducing reliance on new raw materials.

• 2″ layer of Sustain® Comfort Foam (approx. 2.6 lb, 10 ILD) for plush contouring and pressure relief with much better durability than typical low-density foams.

• 1″ FT18200 latex-infused foam for responsive, slightly bouncy comfort and added breathability beneath the top layer.

• Quantum Edge® encapsulated coil unit for edge-to-edge support and reduced roll-off, with narrower-diameter side rails for a stronger perimeter.

• High-density base foam (approx. 1¼”) to stabilize the coil unit and extend the life of the mattress.

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.
