I’m the classic guy that waited way too long to replace my mattress. I went for the Nirvana®. It’s impossible for me to say enough good things about my mattress and the buying experience. You immediately notice the build quality. Everything about the mattress points to a level of craftsmanship you rarely see in products these days. You can tell the people that make it really care about quality. The ultimate test is quality of sleep. It took me a few days to adjust, then I started getting the best nights’ sleep in a long time and I was waking up with less stiffness. Within a few weeks my chronic lower back pain disappeared. Since my weight and exercise regime didn’t change, I can only attest the pain going away to the Nirvana. Put a good nights’ sleep at the top of your list, and get a Shovlin mattress to make it happen.
