What mattress has the most coils?

Gainsborough lists the Mayfair 11,000 with 11,000 individual pocket springs, but the listing does not state a mattress size.

A separate Mayfair listing advertises 1,000 individually sewn pocket springs without identifying the size basis.

The Saatva Classic lists 1,300 total coils for Queen (884 wrapped and 416 base) and 1,608 for King (1,088 wrapped and 520 base).

Another Mayfair listing names a 13.5-gauge Bonnell spring unit but gives no count in its product description.

The 4 primary support-core coil types are Bonnell, offset, continuous-wire, and pocketed.

Support-core coils

Saatva lists wrapped coils and base support coils separately, with a combined total.

• Saatva lists 884 wrapped coils and 416 base coils in its Queen Classic.
• The listed Queen total is 1,300 coils.

Perimeter coils

Some manufacturers may add low-gauge coils around the mattress perimeter to strengthen edge support.

• Mattress & Sleep Company says its foam perimeter removes spring rows, reducing both spring count and sleeping area.
• The Mayfair 5,000 listing names PowerEdge for extra edge support, but does not say whether it adds to the spring count.

Bonnell, offset, continuous-wire, and pocketed are the 4 primary support-core coil types.

Bonnell coils

Bonnell is one of the 4 primary support-core coil types.

• Bonnell coils are hourglass-shaped and knotted at the ends.
• Avocado says a coil’s gauge, height, and turns shape how firm it feels.

Offset coils

Offset is also one of the 4 primary support-core coil types.

• Sealy says adding an extra turn provides more working wire for durability and responsiveness.
• Tuck says turns indicate softness or firmness and how supportive a mattress will feel.

Pocketed coils

Pocketed coils are one of the 4 primary support-core types.

• For noise and motion, Sleep Foundation says pocketed coils tend to reduce noise and isolate motion better than other coil patterns.
• Saatva’s table separates wrapped, base-support, and total counts.

The Marshall Curated Series lists 650 coils; that count sits within Sleep Foundation’s 400 to 1,200 Queen range and above Saatva’s 400-coil Queen rule of thumb.

In the InnoMax Spirit listing, coil counts differ by size.

The coil count does not identify the coil type or the metal quality.

Support may vary with coil type, gauge, total count, and overall mattress design, according to Sleep Foundation.

Avocado says a coil’s gauge, height, and turns shape how firm it feels.

Gauge and turns can help explain firmness and feel.

Coil gauge

Gauge describes wire thickness, and a lower gauge number means thicker wire.

• GoodBed describes 12.5-gauge wire as thicker and stronger than 16.5-gauge wire.
• Sleep Foundation describes 13-gauge coils as thicker than 17-gauge coils.
• The Saatva Classic uses 13-gauge base coils for durability and 14.5-gauge wrapped coils for comfort.
• Avocado says a coil’s gauge, height, and turns shape how firm it feels.

Coil turns

Turns are the number of times a coil is wound.

• Tuck says turns help indicate softness or firmness and how supportive a mattress will feel.
• Sealy says adding an extra turn provides more working wire for durability and responsiveness.

Sleep Foundation says significant motion may transfer across the bed.

• Saatva says 884 individually wrapped coils respond to movement and limit motion transfer.
• Pocketed coils dampen movement transfer across the bed, according to Tom’s Guide.

For a fair coil-count comparison, verify the model, mattress size, and which coil layers make up the advertised total.

1. Check whether Saatva’s table lists wrapped, base-support, and total coils separately.
2. Check that the Saatva help page names the Queen Classic and its 884 individually wrapped coils.
3. Check whether a Mayfair total combines full-size and mini springs; its 3,000 listing separates 1,000 full-size and 2,000 mini springs.
4. For the Mayfair 11,000, note that the listing describes multiple spring layers but does not give a size basis.
5. Avocado directs readers to its separate per-model coil-count and innerspring page.

Can a split King have a different coil count from a standard King?

The sources do not establish whether a Split King can have a different coil count from a standard King. Big Fig lists 1,600 coils for King and California King.

Can two mattresses with similar coil totals feel different?

Yes, two mattresses with similar totals may differ in support because coil type, gauge, total count, and overall design can matter. Lower-gauge coils are thicker and more supportive, while higher-gauge coils are thinner and more flexible; some constructions use thicker wire with fewer coils or thinner wire with more.

Why are full-size high-count coil systems hard to find?

The sources here do not establish why high-count Full-size coil systems are hard to find. Saatva's rule-of-thumb minimum is 300 coils for Full versus 400 coils for Queen, but those figures do not explain availability.

Does a small coil-count difference matter?

A higher coil count does not necessarily mean better comfort or support because the total does not describe coil quality. Saatva describes its lower-gauge coils as thicker and more supportive; Avocado lists micro-coil and base-coil counts separately.
