Our Verdict

Kirkland Stearns & Foster Pillow Top Lakeridge

Casper Cooling Select Hybrid

The Kirkland Stearns & Foster Pillow Top Lakeridge and the Casper Cooling Select Hybrid are pretty evenly matched overall, but they have a few differences to consider. Go for the Kirkland Stearns & Foster if you sleep on your side, since it offers a little extra pressure relief, which helps cushion your shoulder in this position. Its excellent motion dissipation also makes it a better choice for partnered sleepers, especially if one tends to toss and turn. The Casper, on the other hand, offers more support for back and stomach sleepers. It's also a better choice for hot sleepers, since it transfers more heat away from you throughout an eight-hour night.
