We have had our Temperpedic for about 3 years and I never had a better nights sleep than with this mattress. We also got the split king set up--like two twin beds set next to each other. I do get a little warm, so usually just use a top sheet. Bought two sets of split king sheet sets at overstock.com that are great. Or you can just buy 2 long/deep fitted sheets. 1 king flat and the pillow cases separately.
