Innerspring mattresses with interlocking coils feature a connected coil system designed to provide a responsive, supportive feel across the sleep surface. Also known as Bonnell coils or traditional innerspring coils, these hourglass-shaped springs are joined together to distribute weight and support the body as you move throughout the night. The interconnected design can create a firmer, more buoyant feel that appeals to back and stomach sleepers, as well as anyone who prefers the familiar support of a traditional innerspring mattress. Many models also include comfort layers made with quilted fabric, foam or fiberfill to add cushioning above the coil system, helping create a balanced combination of pressure relief and support. A mattress with interlocking coils may also offer strong edge support and dependable durability, making it a practical choice for guest rooms, primary bedrooms and shoppers looking for an affordable mattress with a classic feel. Because the coils move together, interlocking coil mattresses can transfer more motion than individually wrapped pocketed coils, so couples who are sensitive to movement may want to compare both options before choosing a mattress. Consider the mattress firmness, comfort materials, coil count, height and sleep position to find the right fit. Trying different innerspring mattresses in a store can also help you compare support and comfort, while a Mattress Firm Sleep Experts® team member can help you explore mattresses that match your preferences and budget.

What are interlocking coils in an innerspring mattress? + -

Interlocking coils are connected steel springs arranged in a network beneath the mattress comfort layers. Their linked design creates the core support structure of an innerspring mattress.

How are interlocking coils different from individually wrapped coils? + -

Interlocking coils are connected to one another, while individually wrapped coils are enclosed in separate fabric pockets. This difference affects the mattress construction and the way the coil system is arranged.

What materials are used above interlocking coils? + -

Innerspring mattresses with interlocking coils may include comfort layers made from materials such as foam, gel foam or fiber padding. The specific combination varies by mattress design.

What mattress feel is common with interlocking coils? + -

Mattresses with interlocking coils are often designed with a more traditional innerspring feel. The overall feel also depends on the comfort layers, upholstery and mattress cover.

Can an interlocking-coil mattress have a foam comfort layer? + -

Yes. Many innerspring mattresses with interlocking coils combine their steel coil core with one or more foam comfort layers. This construction blends a traditional coil system with cushioning materials.
