Lull vs Puffy Original
These are the closest competitors. Lull is slightly firmer with a 365-night trial. Puffy Original has better pressure relief for side sleepers and uses adaptive cloud foam that responds to body temperature. Puffy's 101-night trial is shorter, but its foam technology is more advanced. For side sleepers: Puffy wins. For back sleepers on a budget: Lull wins.
Cooling Foam Alternative
Puffy Lux — From $999 Queen
Premium memory foam with cooling gel. 101-night trial, lifetime warranty. Made in USA.
Lull vs Amerisleep AS3
Amerisleep AS3 ($1,049 queen) uses proprietary Bio-Pur open-cell foam that outperforms Lull's gel memory foam for cooling and responsiveness. Amerisleep also has better HIVE zoning for lumbar support. Worth the $300 premium for those who prioritize sleep quality; Lull is the right choice for budget-first shoppers.
Weaknesses
- Only 10-year warranty (industry average — not exceptional)
- Standard gel foam cooling — runs warm for very hot sleepers
- Limited firmness options (medium only in Original)
- No edge reinforcement — foam edges compress noticeably
Verdict
Lull earns 3.8/5. It's a solid, dependable mattress with an exceptional 365-night trial that few competitors match. But at $745+ queen, Puffy Original offers better foam technology at a comparable price, and Sweetnight's hybrid options deliver superior cooling and support for similar money. Best suited as a low-risk guest room or starter mattress.
FAQ
Is Lull mattress good for side sleepers?
The Lull Original (medium, 6/10) works for side sleepers between 130–200 lbs. Lighter side sleepers may find it too firm; heavier sleepers may experience hip pressure. Puffy Original provides better pressure relief for dedicated side sleepers across a wider weight range.
Does Lull mattress sleep hot?
The gel-infused top layer moderates temperature for average sleepers, but hot sleepers or those in warm climates may find it runs warm. It doesn't have the open-cell foam structure or coil system airflow of premium alternatives. A breathable cotton or Tencel cover helps, and using lighter sheets improves temperature regulation.
Is the Lull 365-night trial real?
Yes — Lull's one-year trial is genuine and among the longest in the industry. Returns are free and straightforward. This is Lull's strongest competitive advantage and significantly de-risks the purchase for hesitant buyers.
