Why Buy a King-Size at US-Mattress?

King size mattresses are the largest of the standard mattress sizes, almost in the shape of a square. The dimensions measure 76 inches by 80 inches (or 6’4” by 6”8”), providing spacious comfort. The King size is usually the most expensive of any given model. However, because of the popularity of the King, the value per square inch only costs more than the Queen size. That means for your money, you’ll actually get better value with the King mattress than most of the smaller sizes.

As the largest of the standard mattress sizes, the King is ideal for couples where one or both partners are active sleepers. Their movements would cause them to disrupt the other sleeper in smaller beds. The King size is almost exactly the width of two Twin XL size beds put side by side (which is a split King), meaning plenty of space on each sleeper's half of the bed. For good value, extra space, or just the most luxurious sleep possible, King mattresses are the best option. They're the largest size commonly manufactured and the epitome of comfort in the master bedroom. King beds are big and heavy, so make sure to measure your space to ensure a good fit!

US-Mattress carries a wide variety of King mattresses, with everything from plush to firm from a number of well-reputed brands. Ask our team of experts to help you find your best fit, they are ready to help you get the right bed at the best price.
