Key Advantages
Why Choose Purple
- GelFlex Grid sleeps noticeably cooler than memory foam
- Unique buoyant feel — no body heat trapping
- Better edge support and bounce
Why Choose Lull
- Stronger motion isolation for couples
- Classic memory-foam hug for side sleepers
In-Depth Analysis
Shoulder pressure relief is essentially tied on our ratings. Both work well for strict side sleepers under 200 lb. Heavier side sleepers should consider stepping up to Purple Hybrid Premier 3 or 4 — the standard models on both sides aren't engineered for sustained loads above 230 lb.
Our Verdict
Neither model has a documented side-by-side lab result here. Choose using available construction information and verify the current seller policies.
Buying Advice
Choose Purple if you sleep hot, change positions a lot, or specifically want the buoyant grid feel that no other mattress replicates
Always try Purple in-store before buying — the grid feel is genuinely polarizing and roughly 1 in 3 sleepers dislikes it
Heavier sleepers (over 230 lb) should look at Purple Hybrid Premier 3 or 4 instead — the standard models on both sides aren't engineered for sustained heavy loads
Couples specifically considering Purple should know its motion isolation is roughly average; if partner disturbance is your top concern, Lull is meaningfully better
