This is probably going to be the longest review Purple has ever received, but I want to start from the beginning with my experience because I relied heavily on the reviews of other people before making the "life-choice" of what mattress to purchase. I knew what I wanted in a mattress; support for my lower back and to never experience "the dip" - which so commonly occurs with every single mattress out there - ever again. I had a memory foam mattress before I bought my Purple mattress. On a day-to-day basis, I do not have any back pain. I only had lower back pain in the morning so long as I was in bed for longer than 6 hours, which would slowly dissipate the more I got up and started to move around. Before my memory foam mattress, I had a typical 'spring' mattress. I bought the memory foam mattress because I thought it was what I needed to help with my lower back pain that I had from the spring mattress. Since that mattress was a hand-me-down, it goes without saying that 'the dip' was deep enough to lose a whole body! So, in short, I've had lower back pain for around 10 years now, all from a mattress. I was ready to take the step and spend my beloved, hard-earned money on a new mattress, but which one?! My parents have a Sleep Number and they hate it, I didn't want another memory foam mattress, I was steering VERY clear of a spring mattress, which then led me right to Purple. As I said before, I read review after review. The final review I read is what 'sold' me. A Veteran who had seen and done it all for the love of his country (Thank you for your service) had MANY body aches, as I am sure you can imagine. He talked about having back pain and how, on the very first night, he woke up the next morning with no pain. "WOW! It's a "magic mattress"!", I thought. He also stated in his review that he bought the whole kit-n-kaboodle; the pillow, the sheets, the mattress protector, and of course, the mattress. I, however, only bought the mattress and the sheets - which are the most amazing bed sheets I've ever owned. Amongst my research, I saw a few reviews that said that it could take a few nights, weeks or even months for your body to get used to the mattress. Ok, makes sense. So, here I go...I make "the purchase", I do some hard core Fed Ex stalking and then ALAS! It's finally here! (side note: I read reviews that warned that this mattress was heavy and that you need two people to move this. Me, being stubborn and very independent, laughed at the warnings. I am here to tell you, this sucker is HEAVY! You most certainly need two people.) Fast forward a month and a half, I still wake up with back pain every morning however, it's not as bad. It's very disheartening spending such a large sum of money (to me, this is a large sum) to not have "the magic" work. Yes, I know, this isn't a magical mattress, but I at least expected to sleep in bed longer than 6 hours at a time. I told everyone I know about this mattress because I was SO excited. Since it's been a month and a half, they're now asking me how I like it. Here's the truth, I don't know! When I lay down at night, I love it. When I wake up in the morning, I am disappointed. Someone said, "maybe it's your pillow". So, my next step is to purchase their original Purple Pillow and hope for the best. Due to just buying a house and buying a mattress, the funds aren't readily available to do so for a while yet. I know the mattress comes with a 100 night trial period, but I honestly don't want to get rid of it because what am I going to purchase instead? (see aforementioned stipulations above) Time will tell, I suppose. Until then, sleep well my friends!
