Avocado Green
What works
Dunlop latex is denser and more durable than Talalay — better long-term firmness maintenance
Higher coil count (1,414 in queen) with 13-gauge steel — more supportive base
Rainforest Alliance certification for latex sourcing in addition to GOTS/GOLS
What doesn't
Standard version is firm (7/10) — not ideal for strict side sleepers without the pillow top
Pillow top adds $400, pushing total to $2,099 for softer feel
Less motion isolation than memory foam alternatives
Birch Natural
What works
Talalay latex comfort layer provides softer, more accessible feel for first-time latex sleepers
Better motion isolation than Avocado due to softer comfort layer
Backed by Helix's operational scale — strong customer service infrastructure
What doesn't
Talalay latex is less durable long-term than Dunlop — may soften faster over years
25-year warranty is good but Avocado's construction may outlast either warranty
Less bounce and support for stomach sleepers versus Avocado's firmer base
