Throughout our testing, both mattresses held strong across our criteria of comfort, performance, breathability, and motion transfer. Our top pick is The Endy Mattress because not only is the quality amazing at a fair price point, but it also performed the best in most of the categories mentioned.

At first glance, the Endy and Casper have similar construction, with three layers of foam - fairly standard for an all-foam mattress. They differ in feel though: The Casper Mattress has more of “bounce,” so you don’t feel snug in the mattress, while The Endy Mattress feels more like what you would expect from a traditional foam mattress, offering comfort and support. This distinction becomes particularly important when you’re factoring in motion transfer, as the “bounce” in the Casper, means it doesn’t eliminate motion transfer as well as the Endy does.

Another similarity in each mattress is their top layer, which uses specific technology to enhance its breathability (this will be a crucial consideration for particularly hot sleepers). The Casper uses perforated foam for a cooling effect, while the Endy uses open-cell foam infused with cooling gel, to keep you at the perfect temperature. We’ll delve into this further.

If back pain is a concern, rest assured that both mattresses offer excellent spinal support. They also relieve pressure points in greater contact areas, such as your hips and shoulders, to prevent overall discomfort. Both the Endy and Casper mattress use ideal materials. However, I recommend The Endy Mattress to ensure you’re getting quality sleep for years to come.
