Copper Harbor Plush Pillowtop

The Capitol Bedding Copper Harbor Pillowtop

Luxurious, Plush Comfort

The Copper Harbor Pillowtop is the softest offering in this Capitol Bedding collection, designed for sleepers who crave a cloud-like surface without sacrificing underlying support. Built with indulgent comfort layers, this model uses ultra-premium foams—including dual layers of 2.5 lb density Serene® foam and multiple gel foam layers—to deliver exceptional pressure relief and gentle conformity from the moment you lie down.

Premium Upholstery Build

Crafted with a thoughtfully quilted cover and reinforced by high-resilience, American-made materials, the Copper Harbor Pillowtop brings a sense of luxury usually reserved for much higher price points. The blend of 2.5 lb density foams in varying ILDs offers both a soft landing and a stable core, giving you support that feels almost weightless.

Best for Side Sleepers and Plush Seekers

This bed is ideal for side sleepers who want extra cushioning at the hips and shoulders. If you often wake up with tension in these areas, the Copper Harbor is likely your match. Back sleepers who enjoy a softer contour may also love the feel, though stomach sleepers may prefer a firmer model like the Superior Mornings Pillowtop or Suttons Bay Plush for more support across the midsection.

Strong Support System

Beneath the luxurious surface lies a Bolsa-style coil system with Quantum Edge support, ensuring long-term durability and minimizing edge roll-off—especially important on softer beds. This system is designed to maintain structure over time, even with the mattress’s plush top layers.

Adjustable Base Compatible

The Copper Harbor Pillowtop works effortlessly with adjustable bases like the Sealy Ease 3.0 or Rize Clarity. Pair it with a base to personalize your comfort and enjoy the soft embrace of this high-end mattress in any position.

From Our Family to Yours

Made in Capitol Bedding’s family-owned factory in Grand Ledge, Michigan, every Copper Harbor Pillowtop mattress is handcrafted using safe, non-toxic certified foams for peace of mind and premium rest.

Looking for something just a little firmer? Try the Suttons Bay Plush for a balance of softness and support, or the Superior Mornings Pillowtop for something with a touch more responsiveness.

For over 50 years Capitol Bedding has been crafting high-quality mattresses rooted in the commitment to providing durable, comfortable sleep solutions. Their innovative approach began with the decision to create a one-sided, no-flip mattress using top-tier materials, particularly high-density foam. This led to the adoption of premium foams like ‘P2536’ (2.5lb density, 36ILD (Initial Load Deflection)), ‘P2560’ (2.5lb 60ILD), and ‘P2426′(2.4lb 26ILD), each tailored to deliver different levels of support and comfort. These materials have stood the test of time, ensuring Capitol Bedding’s products remain among the most resilient and comfortable on the market.

What sets Capitol Bedding apart is their dedication to using higher density foams that outperform the industry standard. Unlike most mattresses that lose their firmness and support over time, Capitol Bedding’s designs use 1.8lb, 2.4 lb and 2.5 lb foams, which experience significantly less firmness loss even after years of use. Their foams, sourced from Future Foam, one of the top producers in the U.S., are chosen for their exceptional quality and longevity, contributing to a mattress that retains its original feel and support far longer than most.

 Key Benefits:
– High-Density Foam: Lasts longer and maintains support better than standard foams.
– Foam Types: P2536 (durability), P2560 (firm feel), P2426 (soft feel).
– Firmness Retention:
– 2.5 lb foam: 8% firmness loss after 10 years.
– 2.4 lb foam: 9% firmness loss after 10 years.
– 1.8 lb foam : 20% firmness loss. (1.5lb and below are typically used in  most other manufacturer’s beds)

– Compared to:
– 1.2 lb foam: 38% firmness loss. 
– 1.0 lb foam: 42% firmness loss.

– Premium Materials: Sourced from Future Foam, a top family-owned U.S. producer of Flexible Polyurethane Foams.

While the use of these premium materials comes at a higher cost, Capitol Bedding believes that better foam makes better, and longer lasting, mattresses—and better mattresses lead to better sleep. Their investment in high-density foam ensures that every customer experiences a durable, supportive mattress that enhances the quality of their sleep for years to come.
