Well being that I had bought 2 Nectar brand memory foam mattresses for my other two children and thought based on the reviews this would be a good buy for my youngest.... all I can say is you get what you pay for. Anyone in the market for this type of mattress spend the extra money and buy a good one. This thing is terrible and not near the quality of the ones I bought earlier. When you sit on it it actually makes a crinkling sound as if it’s an air mattress.  If you weigh more than an 11 year old this is not for you. ( and it did not inflate to 12 inches... not even close)
