FAQs
-
Firmness describes how soft or firm a mattress feels when you lie on it. Firmness labels can vary by manufacturer, so compare the product descriptions rather than relying on the label alone.
-
A pillow-top has an added upholstery layer sewn onto the sleeping surface, while a tight-top has a more streamlined surface without that separate layer. Neither style alone determines overall firmness; the underlying construction also affects the feel.
-
Not every mattress requires a box spring. Some are designed for a platform, a slatted base, or another type of foundation. Follow the mattress manufacturer's requirements for the foundation and any applicable slat-spacing guidelines.
-
Follow the manufacturer's care instructions. Some mattresses can be rotated from head to foot, while others have a designated orientation. Only flip a mattress if it is specifically designed for use on both sides.
-
Check the care label before cleaning. If permitted, vacuum the surface with an upholstery attachment and spot-clean marks using the recommended method. Avoid soaking the mattress, let it dry completely before replacing bedding, and remove the cover only if the care instructions allow it.
