Every Anmiz mattress is crafted when you order it. We assemble all our mattresses in America with care and pride, using only the highest quality, globally sourced materials. We could have settled on cheaper materials and produced our mattresses elsewhere for higher profits, but we've never wavered in our commitment to quality. We believe it's the right thing to do for our customers, our American workers, and our economy.

Every Anmiz mattress features:

• Cover made with organic cotton.

• Guardin™ botanical antimicrobial treatment

• Eco-conscious foams that are CertiPUR-US®* certified to meet their rigorous standards for emissions, content and durability

• Recycled steel coils

• Flame retardant barrier made from natural thistle pulp without toxic chemical sprays or fiberglass

• Base panels on our single-sided mattresses are made with REPREVE® recycled polyester, diverting single-use water bottles from ending up in landfills

*CertiPUR-US® is a registered trademark of the Alliance for Flexible Polyurethane Foam, Inc.

Sit back and relax while we do all the work. Our free white glove delivery includes in-room delivery and set up. We'll even take away your old mattress at no additional cost to you. Just select free mattress removal at checkout.

At Anmiz, we never pressure you to make up your mind quickly. All of our mattresses come with a 100-night home trial, so you have plenty of time to decide whether it’s right for you. If at any point during your home trial you’re not satisfied, just give us a call and we’ll come pick up the mattress and refund your money, less a $99 processing fee to cover our cost of gas and labor for the pickup. That’s it.
