Cranium Furniture - Standard Mattress Box Springs

One of the finest Standard Mattress Box Springs available. We provide 22% more coils than is standard for extra support and durability, and have 50% more coils located in the center-third of the box spring to support the body better (over 60% of our body weight is located in our torso area).

The thickness of our coil wire is an extra heavy duty 8 3/4 gauge compared to the standard 9 � - 10 gauge wire. Even our box spring contains a layer of staple cotton padding for added support for the underside of the mattress. Brass corner guards are installed on all corners, rather than the plastic ones that break off easily, and heavy duty cotton fabric is used on the underside of the box spring, instead of the thin synthetic sheeting that commonly droops and frays easily. You will only get the best with our Royalux Collections!

Natural Organic Box Spring with Wool Wrap

One of the finest Natural Organic Standard Mattress Box Springs available. The Natural Organic Box Spring with Wool Wrap comes standard with the H-2 box spring unit for firm, yet flexible support. As an upgrade option, the Double Diamond Box Spring is available.

Even our box spring contains a layer of organic staple cotton padding for added support for the underside of the mattress, as well as layering of our French wool to provide a natural fire barrier. Brass corner guards are installed on all corners, rather than the plastic ones that break off easily, and heavy duty organic cotton fabric is used on the underside of the box spring, instead of the thin synthetic sheeting that commonly droops and frays easily.
