Yes, most mattresses still include springs, which add bounce; coil-based mattresses are generally easier to move on than all-foam beds. Hybrids typically have a pocket-coil core with foam, latex, memory foam, gel-infused materials, or wool as a buffer. Traditional innersprings are harder to find because most companies phased out the style for lack of demand, though some budget models remain.
GoodBed says most mattresses still include springs. Coils contract and expand under pressure, giving mattresses bounce and generally making movement easier than on all-foam models.
Traditional innerspring styles are harder to find because most mattress companies phased out the older style for lack of demand, though some budget-friendly models remain.
The simplest, least expensive mattresses may consist mostly of springs, with thin foam or padding on top or bottom.
GoodBed says pocket springs have become the most common coil design in the mattress industry.
A hybrid mattress typically has a pocket-coil core with foam, latex, memory foam, gel-infused materials, or wool as a buffer. Hybrid mattresses may also include microcoils for added responsiveness and support.
Definitions vary: GoodBed defines a hybrid as pocket springs with at least 2 inches of specialty foam, while Sleep Foundation defines one as a coil core with a significant foam or latex comfort system.
Sleeptronic describes hybrid construction as all-foam construction coupled with a spring base. It also says traditional spring-and-foam and hybrid mattresses can use a variety of spring types.
The 4 primary support-core coil designs are Bonnell, offset, continuous wire, and pocketed.
Pocketed coils have no direct coil-to-coil connection, though their pockets might connect together.
Bonnell coils are interconnected and move as a single unit.
Continuous-wire coils stay tightly connected and may still transmit some movement under pressure.
Vispring pairs natural fibers with pocket springs rather than relying on dense foam for comfort.
If you want a spring mattress without memory foam, check the full model specs: Restokraft’s 520-count continuous-wire listing does not specify memory foam, while its separate coil series lists quilted gel foam and step-up memory-foam comfort layers.
Traditional innerspring mattresses can be found in maker listings and product catalogs.
Restokraft lists profiles of about 8 to 15.5 inches. Restokraft says regular rotation and flipping can help sleepers enjoy consistent support and performance.
Each Elite collection model starts with a 12.5-gauge offset coil innerspring.
For the model described, Kings Impressions says flipping it each spring and fall distributes wear across both surfaces.
Check the exact model’s care details before assuming the same schedule applies to every two-sided spring mattress.
Coil gauge describes wire thickness; a smaller gauge number means thicker wire.
Typical mattress coils range from 13 to 17 gauge, with 13-gauge wire thicker than 17-gauge wire.
A topper can change an innerspring mattress’s firmness and support, so it is not a neutral add-on.
Sleep Foundation’s testing-method page says a topper can improve motion isolation if the mattress is not overly responsive.
The simplest, least expensive spring mattresses may have only a thin layer of foam or padding on top or bottom.
Coils contract and expand under pressure, giving a mattress a springy, bouncy feel.
Coil-based mattresses are generally easier to move on than all-foam models.
No, pocket coils are one type of innerspring coil, alongside Bonnell, offset, and continuous wire coils. Pocket coils are individually wrapped in fabric, unlike connected coil systems also included under innerspring.
Yes. Bonnell coils are interconnected and move as a single unit.
Hybrid mattresses may also include microcoils for added responsiveness and support. Microcoils and mini coils are typically 1 to 3 inches tall.
Pocket coils minimize motion transfer and noise because each coil compresses independently.
No. Some basic spring mattresses use a thin layer of foam or padding on top or bottom, not necessarily memory foam.
A Restokraft 520-count continuous-wire listing does not specify memory foam in its described construction.
