I've only heard great things about Casper mattresses, and it seems like the product's engineering goes above and beyond what went into other mattresses. It has a 3-layer memory foam construction for support, breathability, and bounce, along with a springy top layer for balanced comfort. There's an open-cell top layer which uses convection and conduction to flow heat away from your body while you sleep to keep you cool at night, and the memory foam layer underneath assists in this process as well.

The mattress you choose will be shipped rolled up in a rectangular box, so you must wait 72 hours after unpacking for it to fully expand. Casper provides a free 100 night trial with these mattresses. If you decide it's not the bed for you within that timeframe, simply contact Casper and arrange for them to come pick it up.

Casper also sells a bunch of sheets to match the size of your new mattress. A number of these are on sale, too, so you may want to get some at the same time. You can save on the Casper Sleep Pillow today as well when you clip its on-page coupon at Amazon. That brings the standard size's cost down to $55.25 from its regular cost of $65. You can find the coupon on the King size version as well.
