Query: Cheapened product

I just received this mattress topper in a twin size and I am very disappointed. A few months ago, I got this same mattress topper in queen size and it was excellent, nice and firm. The twin sized mattress topper that I just received is much, much softer, more like foam rubber than memory foam. I will talk to my daughter about whether it is worth keeping, but you should know, that in my experience, the positive reviews that are posted are for a very different product.
