Douglas Summit Review

Rating: 7.2
Verified
Buy Douglas
The Douglas Summit mattress is a Canadian-made, all-foam mattress with a 12-inch profile and a medium-firm feel. It features three layers of foam, including a gel-infused top layer and a cooling cover made from phase-change material (PCM), which contribute to its excellent cooling performance. The mattress scores highly across various metrics, including motion transfer, response time, edge support, and pressure relief. However, it has low bounce, which may not be ideal for sexual activity. The mattress is suitable for all sleeper types and comes with a 365-night trial period and a 20-year warranty. Priced at C$1,299 for a queen size, it is slightly above average but justified by its high performance.
