First thing I want to complain is company's attempt to drive 5 star ratings by calling customers insisting for a 5 star in return for a gift. Such practices impair trust on Amazon's platform, and now a point has come, when people know that customer ratings and review on Amazon is useless as there are agencies who push such ratings/reviews to push sales.
On the product, my personal feel is: its comforting to a youngster who doesnt have any back issue, I often get a good sleep. However, the mattress does heat a bit and in summers, need an AC. But overall a decent buy. Delivered in time and been using for past one year.
