I've had several other toppers in the past for our king-sized mattress -- one was supposed to stay cool (it didn't); one was cut short by several inches on all sides and really was annoying -- this one is perfect -- its four edges perfectly meet all the way to the mattresses edges that it sits on, and its firm and super comfortable and cushy. We'd had a 3 inch before, but the 4 inch was definitely worth spending a little bit more for the extra support it gives. This is a well-made, quality foam topper -- not all of them are of this caliber. One we had started to disintegrate, as well as become very discolored, in less than a year. We've had this one for over a year and it looks like it's brand-new. Couldn't be happier -- love getting in to bed!
Don't let the review fool you. A California king does NOT come as described. It's supposed to be 72"x84". In reality, it's 70"x79". I understand that the foam isn't going to be cut perfectly, but this type of shortage is just ridiculous. Thanks for saving on dime on my buck!
i bought this Mattress Topper for my granddaughter Sarah who is in college and has a very uncomfortable thin mattress. This was just what she needed and is giving her a good night's sleep. it is very comfortable.and I would highly recommend it.
