After experiencing low back and shoulder pain, I checked back and found that our mattress was 20 years old! Time does pass quickly! I researched many types of mattress then decided to try the GhostBed. My husband was skeptical about buying a mattress by mail but with the trial period, he agreed. Now he loves this mattress and I do too. It really is just right. Not soft, not firm/hard. Support without being hard and soft without being mushy. Great purchase for us.
