I had scoliosis and then had the spinal fusion surgery to correct my Scoliosis. The majority of my back is fused which is great except when it comes to sleep. I've had issues for the past 5 years since having surgery with multiple mattresses and my overall sleep. Where my low-back is fused I've had nagging pain. Once I started sleeping on my LuxeAdapt mattress I've experienced zero lowback pain. The mattress truly does mold to your body, alleviating pressure points!
