True Coil Count in Saatva Classic Queen 11.5"
Saatva Classic coil counts from Saatva's published specs: the combined total of 1,300 coils (884 micro-pockets + 416 Bonnell base springs).
Exactly 1,300 Coils (884 + 416)
Direct answer summary
Consumers are often confused by Saatva Classic's advertised coil count. Saatva's published specifications for a Queen-size Saatva Classic (both 11.5-inch and 14.5-inch profiles) list a total of 1,300 tempered steel coils. This total is split between two distinct mechanical tiers: 884 individually wrapped upper micro-pocket coils (14.5-gauge wire) designed for body contouring, and 416 heavy-gauge Bonnell base coils (13.0-gauge wire) providing structural foundation.
Key points
True Queen coil count is exactly 1,300 coils across both 11.5" and 14.5" heights.
Tier 1: 884 individually encased micro-pocket coils (14.5 AWG) for pressure point relief.
Tier 2: 416 tempered steel Bonnell base coils (13.0 AWG) for foundational pushback.

Checklist
Comparative Spec Verification Checklist
Step-by-step inspection to detect mid-production substitutions and compare component specs.
- 01
Understand Dual-Coil Counting
Recognize that Saatva combines two layers of coils to reach the 1,300 total figure.
Watch for: Do not assume all 1,300 coils are in a single dense pocket coil layer.
- 02
Verify Height Equivalence
Confirm both 11.5" and 14.5" models have identical 1,300 coil counts.
Watch for: The 14.5" model does not have more coils; it uses taller 7-inch Bonnell coils.
- 03
Check Competitor Coil Densities
Compare against single-layer hybrids (which typically feature 800 to 1,000 coils in Queen).
Watch for: Coil count alone does not dictate quality; wire gauge and tempering matter equally.
