King Size Mattress, 12 Inch Hybrid Mattress with Memory Foam , Medium Firm, — mattresses in every size and firmness — memory foam, hybrid, and innerspring.

Key Features

• Medium-Firm Feel That Fits Most Sleepers: We tuned the foam layers to avoid being too soft or too hard. During test sleep sessions, people of different body types felt supported without sinking, especially when switching from back to side. It's a "safe choice" if you're not sure what firmness you like.
• Zoned Support That Helps Your Back Feel More Relaxed: The coils are firmer in the middle and softer around the shoulders. In testing, this design helped keep the lower back from dipping while allowing the upper body to settle comfortably. Users described it as "natural alignment without forcing my posture."
• Strong Edge Support for Real-Life Use: We reinforced the edge coils so the sides wouldn't collapse when sitting or getting in and out of bed. Test sleepers said they felt more secure near the edges-important for couples who use the full width of a king mattress.
• Low Motion Transfer for Couples: Each spring moves independently, which reduced movement felt during partner-motion tests. Sleepers noticed fewer disturbances when someone turned or got up-ideal for lighter sleepers.
• Certified Safe + 10-Year Warranty Made with CertiPUR-US certified foams, free from harmful chemicals. Your comes with a 10-year warranty and arrives vacuum-packed for easy setup. Let it fully expand within 72 hours and sleep easy knowing you're protected.
