Try Before You Buy

Designed and Built in Colorado

Every Basil mattress is proudly built in Colorado by our manufacturing partner in Aurora. Building locally means a lower carbon footprint and exceptional quality control. We see the materials and the workmanship firsthand and can answer real questions about how our mattresses are made.

Firmness You Can Change Your Mind About

Unlike traditional mattresses that lock you into one firmness level, our 3-inch zippered topper layer lets you customize your comfort at home.

  • Soft (3" Hypergel): Engineered for side sleepers and ultimate pressure relief, featuring cooling hypergel technology that contours without trapping heat.
  • Medium (1" Hypergel + 2" Organic Latex): The perfect dynamic balance for back and combination sleepers, pairing pressure-melting gel foam with buoyant latex.
  • Firm (3" Dunlop Organic Latex): Ideal for back or stomach sleepers who need high-density, GOLS-certified Dunlop latex for responsive support and proper spinal alignment.

FAQs

Do Basil Mattresses come with a warranty?

Yes, we stand behind our craftsmanship with an industry-leading 20-Year Warranty.

What makes Basil mattresses different from the other brands you carry?

Basil is our own line, designed by us and handcrafted in Colorado rather than shipped in from a national manufacturer. The biggest practical difference is the zippered topper system, which lets you adjust firmness at home rather than committing to a single feel for the life of the mattress.

Where are Basil mattresses made?

Basil mattresses are made in Colorado by our manufacturing partner in Aurora. Building locally lets us keep close control over quality and materials, and it means a shorter trip from the factory floor to your bedroom.

Can I change the firmness after I buy it?

Yes, Basil mattresses have a 3-inch zipper closure that opens the top layer, allowing you to swap the topper whenever your comfort needs change. Firmness options vary by model, and you can switch between them at home.

The 1-inch CertiPUR-US® base foam shield makes this hybrid mattress compatible with adjustable bases, platform beds, slatted frames, and traditional box springs.
