Our Verdict

Casper Cooling Select

Silk & Snow Mattress

The Silk & Snow Mattress and the Casper Cooling Select are both cheap all-foam models, and while they both offer good performance, especially for the price, they have a few differences that may sway you in either direction. The Silk & Snow offers better pressure relief, so, depending on your body type, it can be a better choice for side sleepers. Conversely, the Casper provides better support, making it a better pick for back and stomach sleepers, again, depending on your body type. If you sleep hot or sleep with a partner, you may prefer the Silk & Snow, since it offers slightly better cooling and dissipates motion more effectively. On the other hand, if ease of movement is your priority, the Casper is bouncier and offers better edge support, both of which make it feel easier to move around on.
