Bests & Worsts Reviews from Amazon

Frustrating...My mattress toppers only partially expanded. Both the original order and the replacement. I assumed the first topper was defective, so rather than take a refund, I got a replacement. I need them for a guest room bed. Both toppers expanded partially in random places but stayed flat in others. They're unusable. I received a refund after the 2nd topper didn't expand so will try a different brand this time. The picture shows the replacement topper after 4 1/2 days.
