Wholesale King Mattresses: Best Deals and Buying Guide at Costco
When shopping for a king-size mattress at wholesale prices, Costco stands out as a reliable destination. The retailer offers a variety of options, including memory foam, hybrid, and innerspring mattresses, each designed to cater to different sleep preferences. Memory foam mattresses are known for their pressure-relieving properties, while hybrid mattresses combine the support of coils with the comfort of foam. Innerspring mattresses, on the other hand, provide a traditional bounce and airflow, making them ideal for those who prefer a firmer feel.

Types of King Mattresses Available at Costco
Costco offers three primary types of king mattresses: memory foam, hybrid, and innerspring. Each type has unique features tailored to different sleep needs.
Memory Foam Mattresses
Memory foam mattresses are popular for their ability to contour to the body, providing excellent pressure relief and motion isolation. These mattresses are ideal for side sleepers and couples, as they minimize disturbances caused by movement. Costco carries memory foam options from brands like Novaform and Tempur-Pedic, offering varying levels of firmness and thickness.
Hybrid Mattresses
Hybrid mattresses combine the support of innerspring coils with the comfort of memory foam or latex layers. This combination offers a balanced feel, suitable for back and stomach sleepers who need both support and cushioning. Sealy and Serta are among the top brands offering hybrid king mattresses at Costco.
Innerspring Mattresses
Innerspring mattresses feature a coil support system with a cushioned top layer. They are known for their durability and breathability, making them a great choice for hot sleepers. Costco’s innerspring options include models from Stearns & Foster and other reputable brands.
