This topper was great for about 2 weeks and then I started noticing the wells on both sides. Now we have been using it for 5 weeks and the top meets the bottom down the center of both wells which are the size of our bodies. It can be turned over but that won't plump the foam back up. Since it's a wedge, you can put the top at the bottom. DEFINITELY NOT worth what we paid -- not even a QTR of what we paid. In fact, had I known it would do this, I wouldn't have paid $10. BAD PURCHASE......BEWARE!
