Investing in a new mattress is always a big decision and has a substantial price tag attached. We often forget that the sheets are almost as important as the mattress. Don’t skimp on inferior bed linens, the quality and price of your sheets should match that of your mattress.

Sheets need to work with a given size, type, and composition of mattress. If you like a firm mattress, then sheets with a high thread count and a more rigid fabric can work well with the bed. If you enjoy a softer bed, the sheets need to be soft and stretchy to conform to the bed. In this case, a lower thread count can work well. If you are hot at night and need a more breathable or moisture-wicking fabric, look for these qualities in your sheets.

For the Casper mattress, the manufacturer has designed sheets that meet the specific conditions of their mattresses. The Casper brand of sheets is specifically designed for the line of Casper mattresses. This line of sheets is available directly from Casper, with one line available at Target and also on Amazon. The sheet sets available from each retailer vary in size, fabric, and availability. Let’s take a look at some particulars of the Casper line.
