It's been 3 weeks of the best sleep we've had in a long while! We put off the decision for a long time. My main concern was I get so hot when I sleep and I didn't want something that would trap the heat to make it worse. In reality, this topper seems to pull the heat away and I'm sleeping better than ever. My husband doesn't use superlatives often, but he has described this purchase as an excellent one. He's able to sleep on his side again without being awakened with shoulder pain. Amazing. If you're thinking about it, don't wait.....you're just missing another night of good sleep.
