Ashley Chime California King Hybrid 12 in Firm Memory Foam Mattress

Our review of the Ashley Chime California King hybrid mattress finds it best for sleepers who want a traditional coil feel with firmer surface support and targeted lumbar pressure relief. The mattress combines 360 wrapped coils for edge support and motion control with a firm high density foam layer and gel memory foam where it matters most, so it suits back sleepers and combinations who need a supportive, cooler-feeling bed delivered in a box for easy setup.

Key Features

• Hybrid construction: 360 wrapped coils provide consistent edge support and reduce motion transfer so partners can move without waking each other.
• Firm support core: High density foam gives a firmer surface that keeps the spine aligned for people who prefer less sink.
• Gel memory foam layer: The 0.75 in gel memory foam offers restorative lower back support and helps dampen pressure points.
• Comfort quilting: 1.5 in soft quilt foam adds a modest cushioning layer to soften the initial feel without undermining overall firmness.
• Boxed delivery: Ships compressed in a box and expands at home; allow 48 hours for full recovery for quick, low-effort setup.
• CertiPUR-US certified: Foam components meet independent standards for emissions, durability and content for greater peace of mind.

Who It's For

This mattress is a good match for adults who prefer a firmer sleep surface with the support of innerspring coils, especially back sleepers and heavier combination sleepers who need consistent edge support. The gel memory foam provides targeted lumbar relief without excessive contouring.

People who want a very plush, hugging feel or a soft pillow-top should look elsewhere, as this model leans firm. Shoppers seeking ultra-plush pressure relief or those requiring a specialized medical mattress may find softer options more suitable.
