    Good topper--FIRM & SUPPORTIVE

    This topper gave us new life for an older sagging mattress. It give a lot of support back! We ordered a king and received the king. Fits our mattress perfectly. No smell out of the box. Back no longer hurts in the morning! Not squishy/sink in feel.

    Delivered a twin size topper, not KING. Total ripoff. Customer service said this has happened before. DO NOT PURCHASE THIS MISLEADING ITEM.
