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
This topper is for our camper that came with a VERY firm mattress. First time we took it out we did not get much sleep. This topper is very comfortable and saved us from having to buy a new mattress.
Like sleeping on a cloud! We have hated our mattress since the day we brought it home. It is very firm. This topper is nothing less than amazing. We are both sleeping much better. Highly recommend it!
