1. 66% of us think you're supposed to replace your mattress every 10 years. They CAN last that long, or longer. But in general, it's every SEVEN years, not 10.
2. 43% of us think it's fine to just catch up on sleep over the weekend. It's better to get a good night's sleep EVERY night. Being tired all week can be tough on your body, and sleeping in on the weekend doesn't really make up for it.
3. 61% of us think that if you have a bad back, a FIRM mattress is always best. In general, that one's true. But not always. Some people do better with a softer mattress, so it varies.
4. Half of us think some people don't DREAM. 52% of men and 46% of women think that's true. But EVERYONE has dreams. Some people just don't remember them.
