I am 62 and bought the Estate Collection Firm Pillow Top mattress with adjustable frame 127 days ago. My old mattress was soft and caused back and hip pain so I opted for the mattress with the firm topper. I am a back and side sleeper. Although the mattress initially felt comfortable and luxurious it started agitating my back and hips and I feel pain within 10 minutes of getting up in the morning that lasts all day. Unfortunately, I cannot return the mattress (trial period expired) and it was a very expensive purchase for me. I'm considering buying a Tempur-Pedic topper to see if that gives my back and hips some relief. I wish I had purchased a mattress with a medium topper instead. The medium one may have given me that hotel level luxury sleep I was striving for.
