Enhanced steel support
Just like the Birch Natural Mattress, the Birch Luxe Natural Mattress is built on a base of 8-inch individually wrapped steel coils. In this premium upgraded model, though, we’ve added even more support and durability reinforced edge support for a sturdy feel across the full perimeter of your mattress.
The Birch Luxe Natural Mattress also includes zoned lumbar support in the coil base, offering additional coil density across the middle of the mattress where your hips rest, helping keep your spine in line and feel supported in any sleeping position.
