Wasn’t sure if this topper would really work since I have a memory foam mattress that’s too soft. However it is awesome sauce!! It gives the right amount of firmness and me and my boyfriend sleep so sound at night. Sometimes I notice that the topper may bulge or stick up in certain areas once we get up, but it’s a quick fix of pushing it back down. I simply think it’s due to it being a memory foam topper on a memory foam bed. Overall an amazing buy plus the process of watching it rise from being rolled it is pretty cool lol.
