Polysleep Sierra Review

Rating: 7.4
Verified
Buy Polysleep
The Polysleep Sierra is a budget-friendly, all-foam mattress designed for Canadian consumers, priced at C$483 for a queen size. It has a medium-firm feel and is composed of a 2-inch comfort layer of poly foam atop a 7-inch support foam layer. The mattress is noted for its minimal sinkage, high bounce, and fast response time, making it suitable for back and stomach sleepers. It scored a 7.69 overall, with strengths in response time, edge support, and sex performance, but weaknesses in cooling, motion transfer, and pressure relief. The mattress has a 100-night trial and a 5-year warranty, which are shorter than average. It is a good option for budget-conscious consumers but may not meet the needs of those requiring better cooling and motion isolation.
