Literal construction difference
- Aviya Mattress Firm
- 13 inches: cooling quilt with 1 inch of 20 ILD, 1.8-density soy-polyblend foam; 1 inch of 35 ILD foam; 1 inch of 50 ILD foam; a Firm-only 1/8-inch firming pad; 850 individually wrapped 8-inch, 15-gauge Queen coils; 1-inch densified-fiber base
- Saatva Classic Luxury Firm (11.5-inch)
- 11.5 or 14.5 inches: organic-cotton-blend cover; 3-inch Euro pillow top; Lumbar Zone quilting; 1/2-inch gel memory-foam lumbar crown; wrapped comfort coils; high-density foam rails; lower triple-tempered steel coil unit
Why it matters: Aviya uses progressively firmer foam and a thin pad directly above one substantial spring unit, so the surface resists compression sooner and feels more straightforwardly firm. That benefits stomach and back sleepers who want strong pushback without paying for a softer luxury top. Saatva layers cushioning and responsive upper coils over a second support unit. The top absorbs more of the initial impact while the two spring stages restore lift, giving shoppers a more refined pillow-top feel and easier movement.
