1 . Having slept on mid-priced mattresses（床垫）for the past 20 years, my wife and I decided to buy a higher quality mattress. Like many other customers, we visited several local mattress stores and were not pleased with either the construction quality or the sales. So, we decided to check on-line to see what was available. And in all the research, Saatva kept coming up over and over again as one of the highest rate mattress factories in terms of comfort, customer service and producing quality. After an afternoon of interest research, we decided to order the 14.5 inch Luxury（奢侈）Firm king-sized mattress.

As someone who has led an active athletic life-style, I have had 5 knee surgeries（手术）, serious neck injuries, and most recently I was recovering from shoulder surgery. Following the recovery from the shoulder surgery, I was unable to return to our old tired bed because it was so uncomfortable. I was so excited the day our Saatva mattress arrived. My wife and I couldn’t wait to get the sheets on it and try it out.

The next few night’s sleep has proved that. No longer do I move and um al night with all my various damaged and surgically repaired joints screaming at me. Sleeping on our new Saatva mattress is like sleeping on a cloud. You close your eyes and it feels like you are floating. The moment you stretch（伸出）out, all the pressure points on all the old aching joints and injuries just disappear. My wife and I both sleep so well on this mattress that t made me realize how badly I had actually been sleeping on our old tired mattress.

The quality of this mattress and the entire buying experience couldn’t have ben any better. The Saatva mattress has really changed my life. I have run out of superlatives so I will wrap it up by saying “Thanks Saatva!”
