My wife and I are baby boomers. We've slept on upper end coil spring mattresses for years. When the first 'memory foam" mattress came to the market, we ordered one. It was like sleeping on a gym pad. Disappointed (and sore) back we went to another good quality coil spring mattress and were comfortable with it for years. Now, much like us, this mattress became weak & saggy. Our sleep suffered and the morning aches and pains grew stronger. Clearly it was time to replace. I researched various mattress types and brands for about 3 months learning more about mattresses than I ever wanted to. Coil spring, gel foam, memory foam, hybrids, etc. - the whole list of opportunities. All claimed to be the most comfortable, best to support your body and durable. I really struggled with buying a mattress on the internet without trying it out in the store but after looking at the customer reviews and comments about customer service with the 100 night test we decided to give it try. Purple was the only truly unique product on the market and the only real new innovation in this industry in a lot of years. Still skeptical, I ordered one of the Purple chair cushions first and we all tried it out. The final determination was made when I set the cushion on our bed for a minute and our French bulldog instantly curled up on it and went to sleep. This dog is a professional sleeper so his endorsement was good enough for us. BTW- you folks at Purple might want to expand into the pet bed market next. I think you'd find a lot of pet-loving buyers there. I ordered a king mattress on Jan 1, 2017. Purple did communicate that they were backlogged with orders from Black Friday & the Holidays. I told my wife that such demand was a good thing because they are obviously selling a lot of units, many by word of mouth I assume from satisfied customers. They've only been in the mattress game for the last 12 months so I'm sure they are dealing with some growth issues. The mattress finally arrived Jan 19. Yes, it was heavy & bulky but it unpacked easily and instantly went to full size when unrolled. No wait, no odor- just instant bed! I had read some reviews that said it may take up to a week to get use to the feel of this new mattress but not for us. From night one- we absolutely LOVE this mattress. We are so impressed we ordered one for our son & his wife and they are anxious for it to arrive. I wrote this review because the vast majority of those I saw during my research were from younger folks and I just wanted to tell my fellow boomers & other more senior folks that this mattress is for us too. Purple cost is in the upper end for the 'mattress in the box via internet" market. Maybe one or two others more expensive and then you get to the whole Tempurpedic & Sleep Number thing costing what a small car would. I would argue that the Purple technology is what sets it apart from all of the others and is clearly worth the price (assuming it holds up). Bottom line- I absolutely recommend this mattress to anyone for who a good night's sleep is important!
