Integrity FAQs

What is a hybrid mattress?

A hybrid mattress is a base of coils topped with several inches of foam or latex, seeking the “best of both worlds”: the pressure relief of foam with the airflow and edge support of an innerspring.

Is a hybrid mattress better than memory foam?

Hybrid mattresses are known to sleep cooler, with more bounce and edge support than all-foam mattresses, thanks to their coil base, which allows airflow beneath the comfort layers. Memory foam works well for close body contouring and motion isolation. Sleepers who want the pressure relief of foam without the "stuck" feeling might prefer the hybrid combo.

Is a hybrid mattress better than an innerspring?

Hybrid mattresses combine the pressure relief and contouring of foam with the airflow, bounce, and edge support of an innerspring. But hybrids tend to cost more than basic innerspring mattresses due to the added materials and more complex construction.

Which is cooler for sleep, hybrid or all-foam?

Traditional memory foam is known to sleep hot because it traps body heat, but today’s manufacturers add gel infusions to mitigate this, as we do with our Conforma Gel. If temperature regulation is a top priority, a hybrid design with a coil base topped with foam can ensure airflow and cooler sleep.

Are hybrid mattresses good for side sleepers? Stomach sleepers? Heavier people?

Hybrid mattresses tend to suit side sleepers especially well, since the comfort layer can cushion the shoulders and hips while the coil base provides support. For stomach sleepers, a firmer hybrid can help keep the hips aligned with the rest of the body. Heavier individuals (over 240 lbs) can benefit from hybrids with a higher coil count, thicker coil gauge, and a more substantial comfort layer for durability and support.

Are hybrid mattresses good for couples?

Hybrid mattresses with encased coils limit motion across the mattress, since each coil moves independently, while still providing more bounce and edge support than all-foam options. Hybrids with strong edge support also make it easier to use the full width of the bed without feeling like you'll roll off, which matters more when bed-sharing.

What's inside a hybrid mattress?

A hybrid mattress typically has three main components: a coil support core (usually encased coils), a transition layer of firmer foam or latex to smooth the transition between coils and comfort layers, and a top comfort layer of memory foam, latex, or polyfoam for cushioning. Different manufacturers use different materials and thicknesses on their hybrid options.

What are encased coils? Why do hybrids use them?

Encased coils are individual springs in their own fabric pocket, which allows them to compress and expand independently, instead of as a unit. Hybrid mattress manufacturers use encased coils because they reduce motion transfer between sleepers.

How many coils does a hybrid mattress need?

Monarch’s Integrity queen-size hybrid mattress has 1950 coils, though coil count matters less than coil gauge, coil height, and how the coils are zoned across the mattress. A hybrid with fewer, well-designed zoned coils can outperform one with a higher raw coil count but no zoning or lower-quality steel.

What's the difference between a hybrid and a "mattress with pillow top"?

A pillow top is another layer of cushioning (foam, fiber, or down) sewn onto the top of a mattress, which can be added to either an innerspring or a hybrid mattress to increase softness. When people refer to a mattress as a hybrid, they’re specifically talking about the underlying construction: a coil base paired with substantial foam or latex comfort layers built into the mattress itself, not just added on top.

How thick is a typical hybrid mattress?

Most hybrid mattresses range from 10 to 14 inches thick, with the coil base typically making up 6-8 inches and the comfort/transition layers making up the remaining 4-6 inches. Thicker hybrids usually mean more cushioning in the comfort layer, though the coil base height also plays a large role in overall support and durability. Monarch Rest’s Integrity uses both heavy-gauge coils and thick layers of padding for ultimate comfort.

Do hybrid mattresses use memory foam or latex?

Hybrid mattresses can use either, or sometimes a combination of both, in their comfort layer. Memory foam hybrids offer closer body contouring and a slower, more cushioned feel, while latex hybrids respond more quickly, sleep cooler, and tend to last longer. The Integrity collection offers both options, so you can choose whichever fits your sleep preferences and budget.

Do hybrid mattresses need to be rotated?

Yes, rotating a hybrid mattress 180 degrees every 3 to 6 months helps distribute wear evenly. Most hybrids are one-sided and shouldn't be flipped, since the comfort layer is only on one side.

Do hybrid mattresses have good motion isolation?

Hybrid mattresses with encased coils typically offer good motion isolation, since each coil compresses individually and the foam comfort layer helps to absorb motion.

Do hybrid mattresses work well with adjustable bases?

Hybrid mattresses can be compatible with adjustable bases. However, flexibility depends on the coil design — always check the manufacturer's specifications, since some coil systems aren't built to flex repeatedly at the head and foot. Hybrids marketed specifically as "adjustable base compatible" are the safest choice if you know you'll be using one, and Monarch Rest’s Integrity falls into this category.

Does a hybrid mattress come with a warranty?

Monarch Rest’s foam mattresses come with a 20-year warranty covering workmanship defects or component failures, including impressions exceeding ½ inch (first 10 years) or 1 inch (next 10 years). Review our full warranty for more details.
