I received a free mattress to try out and review. I chose the BeautyRest Harmony Lux Firm. The mattress is definitely firm, too much for my liking. It took over 2 weeks to break it in. My partner and I both have aching bones from old age and arthritis. We did not enjoy the mattress the first week because of the firmness, but after 3 weeks we have adapted to it. I wish it had a thicker quilted top which would help with pressure points. The layers of memory foam work well for sleeping on your back, but not for me, who normally sleeps on my side. Both of us are plus size people and the memory foam is starting to give where we sleep. I give it 3 stars for the firmness, 2 stars for the hard memory foam and low amount of quilting.
