Backstory: Last summer I had pulled a muscle in my lower back. After months of healing I was still experiencing minor pain, specifically the right side of my lower back. This is also the side I sleep on and I find it rather uncomfortable not to sleep this way. Obviously when my back was healing I didn't sleep on it, but I found myself wanting to go back to my old habits after it healed, since some nights it didn't hurt, but other nights it started acting up. My old mattress was well past its prime and I knew half of my pain was due to that springy nightmare. After researching different types of mattresses, I settled on the Purple. It arrived shortly after my purchase, right at my doorstep, no dealing with delivery trucks or scheduling. It comes vaccuum sealed and a letter-opener like cutter gets rid of the plastic easily. The mattress literally inflated before my eyes and I could immediately lay down and take a nap. Yes, it had a "brand new" almost sweet and nutty odor, but it airs out after a few days and is non-toxic. As someone who was used to a firm mattress I found the Purple almost too soft, something I quickly adjusted to because I was used to sleeping on a rock. It comes with a mattress cover, which is a good feature for someone who likes keeping their mattress fresh and clean (which, who wouldn't). It's easy to unzip the mattress cover and not too difficult to get it back on. With my old mattress, I had to use one of those memory foam toppers, but once I got the Purple I gladly threw that thing in the trash! As with any new mattress, you should expect an adjustment period. Even with a fantastic mattress like the Purple, my body still had to get used to not being as tense when I sleep. However, after about three weeks on the Purple, my back pain, which acted up only when I laid down, was gone for good. I've also found that sleeping on my back, which I used to find impossible to do on any previous beds I've slept on, is possible on the Purple. I also found myself falling asleep quicker and staying asleep throughout the night. Which leads me to the one problem I have with this mattress - it's too comfortable. I literally cannot get myself to get out of bed in the morning. This isn't an exaggeration, because as someone who is self-employed and has no set schedule, I find myself sleeping in more often than not. I sleep so deep I cannot hear my alarm, even when it's on the highest setting. After three months I have gone from an early riser to sleeping in, but it's all good for the sake of the best sleep I've gotten in years. I've officially been sleeping on this mattress for three months. I'd recommend the Purple Mattress to anyone. I think it's a great fit for people who struggle with sleep, whether for back pain or trouble falling/staying asleep. It's worth the investment. Just make sure to also invest in a great alarm clock because you will never want to leave bed.
