Review: Awesome mattress! - This matress is the perfect firmness for my bad back. I sleep on extra firm. I do have one small complaint. I wake up with my knee in the indention from the sewed in circles on the top. This make my knee ache. Any recommendations on how to fill in the circles without losing any firmness on mattress? Toppers would defeat the purpose of getting a firm mattress.Also some people in the reviews didn't like the inital foam odor. It did not inflame my asthma & went away in about 3days so if u have an extra room. It airs out quickly. I absolutely love this matress!
Review: FINALLY AN ACTUAL FIRM MATTRESS!!!! - My fiance has a metal pelvis from an accident and he would rather sleep on the floor or couch than my bed. I've gone through 2 other mattresses that claimed to be firm but have actually sunk in with a permanent indentation. He hadn't slept in the same bed with me during the night in over 4 years. Last night was the first night he got really good sleep. Normally hell get about 3or 4 hrs, but he got a full I hoirs of sleep. My son won't stay off my bed either. He likes it so much, I keep catching him sprawled out over my bed every time I turn around. I said can't tell you how happy i am to have finally found an extra firm mattress that was TRUE TO ITS WORD!
