3" topper is sufficient for 130lb body, but for 180lb body it's not enough. Also topper needs holsters of some kind on the corners to keep it in place. we have an adjustable base which contributes to slipping but just the transfer of in and out makes the topper slip out of place too.
Admittedly it was a difficult purchase due to finances. However probably the best investment I've made. My wife and I sleep on a split king every night. We've since purchased a fifth wheel trailer that now has threeTempur-pedic toppers. I wouldn't sleep without one. I would highly recommend this mattress to anyone who wants to wake up feeling rested and rejuvenated with no more back pain. We also love our Tempur-pedic pillows. Sincerely happy, The Hawes
I had purchased a hybrid mattress that seemed would work for my back and shoulder pain. It didnt work so decided that we should have bought memory foam. Since we did not want to buy a new mattress we searched out a mattress topper. Im a side sleeper and spouse back sleeper and this has been excellent. We are no longer tossing and turning.
