Helix Plus vs Big Fig: Heavy Sleeper Showdown
Bariatric heavy-sleeper showdown: 13.0-gauge custom pocket coils + latex (Helix Plus) vs hand-tufted 1,600 coil system + 32 ILD foam (Big Fig).
Hand-Tufted Big Fig vs Contouring Helix Plus
Direct answer summary
The Helix Plus and Big Fig are engineered specifically for larger bodies (250 to 500 lbs). Big Fig uses a traditional heavy-duty build: 1,600 pocket coils in King (15-gauge with 13-gauge border), 32 ILD dense polyfoams, and 16 hand-tufted rosettes that physically lock layers together to prevent shifting. Helix Plus uses high-density memory foam, 4.0 PCF UltraDense foam, and reinforced 13.0-gauge TitanCore coils, providing slightly deeper side-sleeper pressure relief.
Key points
Big Fig uses 16 hand-tufted rosettes that mechanically lock layers, eliminating glue failure.
Helix Plus uses dense memory foam over 13.0 AWG coils, offering softer side-sleeper cushioning.
Big Fig feels firmer (8/10) for back/stomach sleepers; Helix Plus feels medium-firm (7/10).

Checklist
Comparative Spec Verification Checklist
Step-by-step inspection to detect mid-production substitutions and compare component specs.
- 01
Choose by Sleep Posture
Back and stomach sleepers over 250 lbs should choose Big Fig; side sleepers should choose Helix Plus.
Watch for: Side sleepers may find Big Fig's 32 ILD dense foam slightly too firm on shoulders.
- 02
Check Matching Heavy-Duty Base
Ensure you order the Big Fig foundation (tested with 18 cross slats) or a heavy-duty steel frame.
Watch for: Using a standard flexible box spring under either bed voids the warranty.
- 03
Check Warranty Sag Depth
Big Fig warrants sagging at 1.0" for 20 years; Helix Plus warrants at 1.5" for 15 years.
Watch for: Big Fig offers superior 1.0" sag protection for heavy individuals.
