I firmly believe the secret to a great bed is a mattress topper. While I love a good hard mattress (attribute it to years visiting ryokans in Japan and sleeping on the floor), I also love the sensation of sinking into a bed. Years ago, I invested in a thick down mattress topper, and I've slept comfortably ever since.

All sizes quoted are for a standard king topper but are also available in twin, full and queen sizes.
