Innerspring Mattresses

• Innerspring: a coil unit does the support, with a quilted top or thin padding. Bouncy, breathable, easy to move on, usually strong edges; more motion transfer, especially with open (unpocketed) coils.
• Foam: no springs. Slow, hugging contour and quiet motion; can sleep warmer and feel “stuck.”
• Hybrid: pocketed coils under thicker foam or latex layers. A middle ground; several beds below are coil-forward hybrids and we label them that way.

Box spring or foundation? Many beds sold as “sets” today want a flat, rigid foundation, not an old-style springy box spring. It looks the same and sits on the same frame. Sealy, Stearns & Foster and Beautyrest say a traditional box spring can void the warranty; Saatva says a box spring is fine. Check the “Base needed” column. Every bed here is researched from brand pages and trusted reviews, not tested by us.
