We have had the mattress for 2 weeks and it still has a peculiar odor. We aired it out for three days before putting in my daughter's room. I regret not airing it out outside for a week or more. At first it made me sneeze. Now it's just a noticeable smell. My daughter says it's very comfortable.
Having tried the iComfort mattress, I have to admit that the Tuft & Needle provided better comfort and support. I have no complaints and have to agree with the statement as described on the website what this mattress truly brings. We love our Tuft & Needle Mattress!
