Bests & Worsts Reviews from Amazon

If I had written this review 30 days ago I would have given this mattress 5 stars, but read on... So we purchased a Purple 4 mattress back in August of this year. For the first 100+ days we slept like the dead on this mattress and couldn't say enough good things about it. Then I started waking up with lower back pain and pain in my right side (I'm a side sleeper, predominantly the right side). I didn't think after 100 or more days of great sleep that my Purple 4 could now be a problem so I slept in our spare bedroom for a couple nights and my pain went away. Went back to sleeping on the Purple 4 and my pain returned. Bummer. Especially after all the money I put out for the king sized mattress, the Purple platform base, two Purple pillows, a Purple mattress protector, and a couple sets of the Purple bamboo sheets. All in all I was into this bed for a little over $4K! I wrote their customer service department and explained my problem, I knew I was over the 100-day return limit by a couple weeks. I was informed they were very rigid about their return policy so there was no getting my money back, however since the mattress had worked so well for so long they stated there may be a manufacturing defect causing my pain and I was given instructions on how to test my mattress (See photo "A."). So I got myself five 1-gallon jugs of water and performed the test on my mattress (See photo "B."). I've sent my results in to Purple's customer service department and now I'm waiting on them to contact me. I'm concerned that not only is there a defect in my mattress, but the replacement they may potentially send me will be a 100-day return from somebody else. I'm not real keen on using a mattress which belonged to someone else. I'm giving this mattress 1 star for now and I'll update this review as the events unfold. We'll see how well Purple honors their 10-year warranty. UPDATE! - I'm going to bump this review up to 3 stars for now. Purple honored their warranty with no questions asked. The paid to have a new Purple 4 shipped to us with white glove setup and hauled the old Purple 4 away. I performed the "Test" on the new mattress (See photo C.) and it passed with flying colors. Now we'll see how it holds up over the next 4 months. You can bet your butt I'll be running the water jug test every time we change the sheets. Once again I will update my review either way and let you know. *UPDATE* So it's now almost the end of April and I've performed the water jug test a couple times on my replacement mattress and it's passed each time. The wife and I are both enjoying our Purple 4 and I've bumped my review up another star. I'll check back in at the 1-year mark and let you know how it's holding up.
