Birch's Luxe organic mattress is again our top pick because it's so well-rounded. It's a great organic model that offers good support, but also a good bit of pressure relief (Birch calls it a medium-firm mattress). It's a little on the bouncy side, meaning that it springs back a good bit when you turn around, which makes it a good choice for back sleepers, since you're well supported.
The Birch Luxe is made of natural materials and uses individually wrapped steel coils, which are topped with layers of organic latex and wool, capped off with a GOTS-certified organic cotton cover. The coils offer full lumbar support and are arranged to cradle your spine but are also stiff around the edge. The Luxe started off with an odd little lip around the edge of the mattress, but after a couple of months that went away. There's no sag in the Birch Luxe, and I had none of the lower-back pain I associate with softer mattresses. The wool and latex top layers provide truly exceptional temperature regulation, and the pillowy top provides a nice bit of softness. (The pillow top is the main thing that separates this from the cheaper, not-Luxe model.)
Birch offers free shipping and a 100-night trial period, and all its mattresses have a 25-year warranty. Birch offers an in-home setup and removal of your old mattress through LoadUp; details can be found on Birch's website. The Luxe arrived completely compressed, and while it was small, it was definitely heavy. If your mattress is headed upstairs, or you're not comfortable lifting bulky, heavy objects, we recommend going for the in-home setup option. —Scott Gilbertson
