King-Size Mattresses For Sale Near You

King mattress are extremely popular, and for good reason. At Sam's Club®, we have a variety of these spacious mattresses available from popular brands. They come in different materials, firmness levels and features.

King-Size Mattress Dimensions

When you hear king-size, most people think of one size: a single mattress that's 76 inches wide by 80 inches long. However, there are other king mattresses to consider. A California king-size mattress, for example, has slightly different measurements. It measures 72 inches wide by 84 inches long, making it ideal for taller people. There's also a super king mattress, which is 80 inches by 98 inches. Be sure you know exactly which size you are getting because it will make a difference when it comes to accessories like sheets, bedspreads and mattress pads.

Pillow Top vs. Euro Pillow Top

These two mattress styles are very similar. They both feature a soft layer of cushioning sewn on top of a typical innerspring mattress. A pillow top king mattress appears to have a separate layer, where a Euro pillow top looks like one cohesive unit. Both provide you with extra comfort on top of firm support.
