• "I bought this mattress 6 months ago and use it on a proper platform bed, no box spring, and it sags so badly in the center already that I wake up in pain."
• "And to make matters worse, it has an indentation from where I sleep most nights."
• "I got this 8 inch mattress less than 4 months. My 30 pound toddler is sleeping on it (on a decent new bed frame) and it's already sinking in the middle."
