Like many others my, husband and I were tired of mattress's in stores. Many felt great for while we were laying on them in the store, but shortly after sleeping on them at home, they were either too firm, too soft or just plain uncomfortable. Both of us having bad backs, hips and pressure issues we tried pillow top, memory foam, latex, gel, innerspring , coil, you name it we had it. My husband was so fed up he was settling with the Stearn And Foster bed we had. I finally convinced him to let me research and look online. With a 100 day trial period and no shipping or return fees how could you go wrong? That is when I came across Purple, Puffy, Nectar and all the other online brands. Quite overwhelmed, I drove my husband crazy looking up reviews and watching you tube bed comparisons. I always ended up going back to Purple. Nervous, my husband wouldn't like the feel of the mattress I convinced him to go to Mattress Firm and test them out compared to other mattress's. The minute he lied down on the Purple mattress he was in love as well as myself. He would lay on The Purple mattress then try a Sealy, Tempurpedic or other store mattress and was convinced Purple was the one!!!! We went between the .3 and .4 for a good hour and a half and decided on the .4. You can really feel the difference between each of the Purple models. The .3 was quite comfy, but the .4 was that much more divine. A turkey weightless feel, but supported and comfortable in all the right areas. We also figured with us both being primarily side sleepers the .4 was slightly softer than the .3. Mattress Firm was awesome. They honored the Purple deal online that gave us two free purple pillows and the sheet set. We also purchased the mattress cover. We ordered everything on a Monday and was picking everything on Wednesday. The bed is heavy in the bag, I definitely got my workout, but once out of packaging it inflated fast with no off gas smell. The pillows had no off gas smell either and no powder some customers mentioned. The mattress cover is a stretchy silky material on the top with a waterproof layer in the bottom side. I immediately washed the sheets, I got in the color slate ( a great color by the way ) and put them on the bed. They are silky and very stretchy. Tonight will be our first night sleeping in the bed and I can't wait to go to sleep. FYI... Purple offers 100 day trial period, but if you purchase through Mattress Firm you get a 120 day trial period. Seriously though, I can't even imagine returning my Purple products. I'm already looking at buying more sheets since they are an amazing quality and the feel of them is this silky light weight feeling. We are looking forward to sleeping well with no more back and hip pain. Thank you Purple for you innovative approach to providing customers with the best support, comfort and sleep possible!!!!
