I had never brought a mattress before this one. I had been searching for the perfect mattress since forever after about a year of being indecisive, I finally decided on a Pillow Top mattress after sleeping on the most comfortable Pillow-Top mattress while on vacation last Spring. I took a chance on this Serta mattress as you can't see nor feel it in person. I have to say it was definitely a good decision. For the first time in years, I sleep well through the night and finally have less back pain as this mattress while comfortable is also really firm at the same time. The mattress was ordered on Tuesday and by Friday (that same week) it was waiting at the carrier service for me to schedule a delivery date and time. For those that may question this mattress know that in my search, I found a mattress that was pretty much the same and was given a price quote of $1200 (including the $100 delivery fee). OVERSTOCK, was more than half that and for ** extra bucks I got a bed frame. I am more than satisfied. My back, body, legs and ability to finally sleep Thank You!!!!
