Purchased the Reserve Soft and my husband and I both loved the mattress initially. Soon after the 90 day return or exchange window expired we realized the Soft Pillowtop model was not the right fit for us. The top had started to compress and sag where we sleep and a hump between us started to form. My husband also began complaining the mattress was causing back discomfort each morning. When I reached out to Customer Service to explain our experience and that we would like to exchange our soft pillow top for the Medium non pillow top model I was told by the representative nothing could be done since the 90 day window for an exchange had passed and I could file a claim if the mattress sag was already greater than 1.5 inches. Considering S&F is a premium brand and we purchased their top end collection I had hoped for a different outcome when I called customer service and explained our experience.
