The Diamond Independence Medium Hybrid Mattress in a Box, 12" combines a medium feel, foam comfort materials and Dynamic Edge wrapped coils in a 12-inch hybrid. Its mattress-in-a-box format is a practical option to explore alongside the usual questions of feel, size and support.

Try the feel first, then plan the setup

Consider Independence if you want a medium hybrid and are comparing delivery or unboxing options. Test your usual sleep positions and, for a shared bed, movement from the other side. The packaging format is a convenience feature; it does not decide whether the mattress feels right for you.

Foam comfort with Dynamic Edge coils

• Comfort foams: Cushioning materials above the springs.
• Dynamic Edge wrapped coils: A coil support system with reinforcement around the perimeter.
• 12-inch hybrid profile: Foam and springs together make up the full mattress height.

This is a mattress-in-a-box model. Confirm how your order will be delivered, and follow the supplied unpacking instructions; packaging dimensions and expansion time should not be guessed from mattress size.

Make the height work for your bed

Confirm access to your room and how your order will arrive. Use a suitable supporting base and follow the mattress instructions for unpacking and expansion. Use our bed-height comparison to plan the mattress and foundation together. For an adjustable setup, confirm the exact mattress-and-base pairing before ordering.
