Where are Sealy mattresses made?

What's the best Sealy mattress for back pain?

This is a tough question to answer, because there are so many potential causes of back pain. However, Sealy's famous Posturepedic support springs are excellent at providing optimal support. Top mattresses for a supportive feel - preventing aches and pains caused by a lack of support - would include the Blackwood Ortho Elevate mattress and the Arden Elevate Ultra mattress.
