I bought a wool mattress, wool mattress topper, and a self-build bedframe from Shepard's dream and I love the whole set. My boyfriend thinks that it is too firm though. I also got a good laugh when a friend did a "launch and land" on my bed, expecting a bouncy landing only to hear her say "WTF your bed is really hard." My mom has described it as a monks bed.
I sleep well on it, like that it is supporting a small business with sustainable business practices, I am not sleeping in insane / weird fire retardants and chemicals, and I know it will last me a very, very, very long time. Your opinion might differ if you like a particularly soft bed.
