I would give less than one star if I could. Mattress was terrible. After 2 weeks it was sinking in.  Causing back pains. After 6 months it had a 3" deep hole where I slept. AWFUL - Luis & the staff don't care.  Comfort guarantee is bogus - a scratch or dirty spot voids warranty. Luis said trade it in on a more expensive mattress. Are you kidding me. I just flushed $1000 down the toilet. DO NOT BUY ORTHO MATTRESS!
