| Price (Queen) | ~$1,399 | ~$799 |
| Trial Period | 100 nights | 100 nights |

The Sleeping Duck Mach II uses a micro-coil layer beneath foam, giving it a slightly more responsive, hybrid feel compared to the Ecosa's all-foam construction. The Ecosa uses a layered foam system where you can physically rearrange the internal foam layers to change the firmness — a unique feature at this price point.
The Ecosa is significantly cheaper and often goes on sale for $599–$699. For budget-conscious buyers, it represents exceptional value. The Sleeping Duck commands a premium but delivers a more premium in-sleep experience for back and stomach sleepers who need firmer support.
Sleeping Duck Mach II suits back sleepers, stomach sleepers and anyone who runs hot at night (the micro-coil layer improves airflow).
Ecosa suits side sleepers, couples with different preferences (you can adjust each side), and buyers watching their budget.
