King size mattresses, also known as king mattresses, offer tremendous comfort, support, and space. King size represents the largest conventionally available bed size. Standard king size mattress dimensions measure 76 inches long by 80 inches wide. If you seek a comfortable, high-quality large mattress, then Rooms To Go is the place for you. With a wide range of styles and various levels of pricing, we can meet your specific needs. Some king mattress styles offered at Rooms To Go include firm, low-profile, memory foam, pillowtop, and plush. Knowing that value matters, we keep our king size prices as low as possible and offer frequent king mattress sales. And we offer brand names you can trust at prices that won't break your wallet.


At Rooms To Go, you'll find the perfect king mattress or king mattress set to fit your favorite bedframe and complement your sleeping style. For luxurious slumbers, consider our comfortable plush mattresses with soft pillowtop cushioning. Many of our innerspring king mattresses offer firmer sleeping surfaces and feature multiple layers of breathable foam for adaptive support. For maximum comfort and convenience, our king size mattresses boast allergen and dust mite resistance, and many selections include specialized systems that minimize pressure points and reduce motion transfer.


Each of our king mattresses is made with your comfort in mind. Tall people have to sleep, too. So, whether you're looking for a king mattress or related accessories, we have what you need. And with affordable pricing, the only issue you'll have is getting out of bed in the morning. Discover the best king mattress for you at Rooms To Go.
