My wife and I purchased the Simmons Beautyrest NXG 400 plush pillow top mattress, it was our first mattress purchase. We were very happy in the beginning, after researching many options we thought we had made the best decision. It's been about 4 years now and lately my wife is so uncomfortable that she is constantly complaining about the negative effects of this product. The mattress does not support the spine at all, it creates pain throughout her back, hips and legs. She has to use 5 pillows and at times a back brace to sleep without interruption. She knows what she is talking about she is a Physical Therapist specializing in the spine. We basically have hammocks on each side of the mattress with a lump in the middle and on my side of the bed we have a bulge sticking out about 4" on the base. The mattress is completely failing! I contacted the store where we purchased and they sent out a person to inspect. A few weeks later we got a response in the mail, our warranty was voided because of a very simple stain on the mattress. We now know to purchase a mattress cover in the future. Recently I went into the store where we made the purchase to look at replacing the mattress, what a shame I have to do this. While I was there I mentioned the situation to the sales person he agreed that the mattress was completely failing and should be replaced but mentioned that unfortunately a stain voids the warranty. I'm not trying to pull a fast one on them, this is a legitimate problem and argument. I am not satisfied with what they did to make up for it, they just said use your warranty refusal letter to get a discount at the store. Great! It's basically the BS discount that every mattress store uses, jack the price up so that when you lower the price they think they are getting a good deal. Do not buy this mattress, in fact do not buy from Simmons at all. How does a mattress company that has been around as long as Simmons put out such a poor product? Why didn't they do some sort of recall? They may have kept me from writing this review if they had just done the right thing and made up for their wrong. I am a Medical Sales rep working for a distributor and I am very familiar with warranties and companies that handle them properly. Simmons has been the worst. Don't trust their products!

We bought the Simmons NXG Apex mattress about a month ago and love it. The top has NXG which is very comfortable and forms to your shape but also allows you to roll over easily and the foam rebounds right away. Under the foam the mattress seems to be one of the best and gives great support. I am 230 lbs and my wife is 140 lbs. We no longer disturb each other while sleeping because the mattress absorbs our movements.

After trying many mattresses this one seems to be the best of all worlds. I would recommend it strongly.
