Bests & Worsts Reviews from Amazon

I bought this one for my daughter’s bed hoping it will be perfect for her bed (twin size) it was delivered yesterday morning 10/29/18 so as soon as we got it we opened it up and let it expand.. within an hour it expanded a lot.. my daughter was so excited to sleep on her new bed. After more than 24 hours the MATTRESS DID NOT EXPANDED THE WAY IT SHOULD BE. It said 5inches??? NO! Clearly it is just 3inches or so. Its kind of filmsy too! I AM SO VERY DISAPPOINTED. The phone that we compare it is just iphone 7 so its just small. Will be returning this for sure!
