Bed is a black hole of restful slumber
We purchased the Serenade (cushion-firm) and we both love it. My partner is a back sleeper and I do it all (side, back, stomach) and it's perfect. Note, the mattress is not firm. And I have to say, Naturepedic's cushion-firm description didn't make sense to me until I was able to sleep in the bed. You do sink into it a bit but feel supported throughout the night. If it's helpful for others to know, soft beds destroy my body, so I do think this is a perfect in-between of firm and soft.
