Bests & Worsts Reviews from Amazon

I'll start with the good... Shipping was INSANELY fast. Order on Thursday and delivered on Saturday (yes Saturday!). Now for the bad... My first night sleep on this mattress may well be the worst night's sleep I have ever experienced! I am a side sleeper and upon awakening I could barely move my left arm. This was Sunday morning. It's now Wednesday and my entire shoulder area is still very stiff and painful to move :( If you're a back or belly sleeper or have enough personal cushion this mattress may be fine but I'm thin (140 lbs) and this mattress is causing me pain beyond belief. I have ordered a $100 plush topper in the hopes that I'll be able to make this mattress work but I am very disappointed in it thus far.
