We ordered this mattress based om high reviews. My husband and I both regular size persons, not obese, have been sleeping on the mattress since July. We have rotated it twice because of the indentations which would not go away. However, the large permanent indentations have caused the mattress to be unusable in less than a year. We purchased a new mattress last week to replace this one and are going to have it disposed of when the new mattress arrives tomorrow. New mattress is not from Wayfair.
