We made the mistake of buying an extra firm mattress. I first purchased a feather topper thinking that would make our bed more comfortable but you need to fluff frequently. The foam topper has given us the best night's sleep in the longest time. We place the feather bed on top of the foam and it's perfect! When you get out of bed you can watch the bed reset itself. Cool huh? And we both don't have stiffness in the joints like before. The only problem is that our elderly cat had to get used to the extra half foot as she was struggling to jump up. She has since gotten used to it. I'm thinking about a footstool myself as I'm rather short. We were to excited to wait for the bed to air out. I didn't notice anything stinky and I do have a sensitive sense of smell. My husband and I are so happy with this purchase. Good price considering the thickness!
