Construction & Materials
| Layer | What It Does | Details |
|---|---|---|
| Organic-cotton blend cover | Breathable, soft hand, cleaner sleep surface | Treated with Guardin botanical antimicrobial |
| Gel-infused comfort foam | Initial pressure relief and cooling assist | CertiPUR-US certified foam |
| Micro-coil layer | Responsive support, airflow, and durability | ~1 inch recycled steel coils, ~18-gauge, zoned for lumbar + edge |
Overall profile is approximately three inches with a one-inch micro-coil layer under foam. Exact specs may vary slightly by size.
Feel & Performance
The micro-coils add a gentle lift you will not get from flat foam pads. You get contour from the foam up top, with springs pushing back to keep your hips from sinking too far. The center-third reinforcement helps posture for back and stomach sleepers.
Air circulates through the coil layer and the organic-cotton blend cover breathes better than many knit synthetics. If you run hot on memory foam, this hybrid layout is a smarter play than a dense three-inch slab.
Perimeter-reinforced micro-coils give the topper a more stable sit edge and reduce that “roll-off” feel, especially on softer mattresses.
Foam above the coils dampens most movement. You will feel a touch more bounce compared to an all-foam topper, which helps with repositioning.
Who It’s Best For
- ✓Back and stomach sleepers who need lumbar lift without losing pressure relief.
- ✓Hot sleepers looking to avoid heat build-up common with thick memory-foam pads.
- ✓Anyone wanting to extend a mattress’s life or tune up comfort without buying a new bed.
If your base mattress is severely sagging, no topper will fully fix it. Consider a replacement in that case.
Pros & Considerations
- Zoned micro-coils for lumbar and edge support.
- More breathable than dense foam toppers.
- Organic-cotton blend cover with antimicrobial finish.
- 180-night home trial and free shipping.
- One-year topper warranty is shorter than mattress warranties.
- Slight bounce may not suit those who want a dead-flat foam feel.
- Spot clean only; use a protector if spills are likely.
