King Size Mattresses

About Our King Size Mattresses

At 76"W x 80"L, a king size mattress is the best option for couples. A king size mattress offers 16 more inches of width than a queen size mattress, which is great for partners that want plenty of room to stretch out. For those who need length more than width, the California king is worth considering. It measures 72"W x 84"L — thus it delivers four extra inches of length, but reduces width by four inches as well. Regardless of which you choose, a conventional or California king, if room to stretch out is your highest priority, there’s no substitute for a king size mattress.

One thing to consider before purchasing a king size mattress is the size of your master bedroom. The ideal room size for a king size bed is 13 by 13 feet or larger. If your master bedroom is 10 by 12 feet instead, you’ll still have room for a king mattress, two nightstands and a dresser, but it will be a tight squeeze.

Our King Size Mattress Options

Whether you prefer your mattress firm, soft or in between, we have options for you. Our king size mattresses come in the comfort levels of firm, plush and pillow top, because we understand that everyone has different needs when they sleep. A pillow top king size mattress offers the ultimate softness, while a plush option gives you a medium-firm feel. Firm king size mattresses offer super strong support, but may be uncomfortable for side sleepers.

We also offer options for your mattress’s interior, with a variety of materials to choose from. Our memory foam king mattresses are made with multiple layers of varied density, for ultimate luxury and support. Our innerspring mattresses provide a different kind of support that comes from a network of coils designed to help you get a good night’s sleep. You may prefer our hybrid king size mattresses, which combine both memory foam and innersprings, for the best of both worlds.

Select models of the king size mattresses we carry are layered with latex foam, a new material in mattress technology that delivers ultimate comfort during your sleep. Furthermore, City Mattress is pleased to offer Bed in a Box options in a king size mattress. These mattresses are compressed into a box only a few feet long, and then shipped to your door for easy installation. Last, many of our king size mattresses are adjustable friendly, so you can use them with an adjustable bed base.

Because every sleeper is different, there’s no single king size mattress that we can call “the best.” Which king size mattress is best for you depends on your personal needs and preferences. For instance, if you’re a side sleeper, you’ll want to look at a plush or pillow top mattress for extra pressure relief. On the other hand, if you primarily sleep on your back, you may find that a firm mattress gives you optimal spinal alignment. Speak to one of our Sleep Experts, online or in-store, and they’ll be happy to help you find the right king size mattress for you.

Hybrid mattresses seamlessly blend the traditional support of an innerspring structure with the luxurious comfort and pressure-relief features of memory foam, latex or both of these materials. Investing in a king size hybrid mattress offers a balance of innerspring bounce and memory foam or latex contouring, making it an outstanding option if you value ample space and dual benefits.

A king size memory foam mattress offers a blend of pressure relief and contouring support. It adjusts to your body shape, helping to minimize pressure points that can cause aches and pains upon waking. And if you have a sleep partner, memory foam mattresses are good for movement isolation as well. Coupled with the generous proportions of a king size bed, you’ll have the freedom to move without disturbing your partner’s sleep.

Choosing between a pillow top or euro top king size mattress primarily comes down to personal comfort preference. Both provide an additional layer of padding stitched into the mattress, enhancing the overall comfort. However, there are some key differences to consider:

Pillow Top Mattress:

  • Softness: Pillow top mattresses are generally softer, allowing sleepers to sink further into the bed for superior contouring and pressure relief.
  • Appearance: They present a fluffy, “pillowed” look, offering a luxurious sleeping surface.
  • Feel: Pillow top mattresses deliver a plush, cushioned feel, making you feel like you’re sleeping on a cloud.

Euro Top Mattress:

  • Density: Euro top mattresses are usually denser due to their construction from foam or fiber, which gives a firmer feel.
  • Attachment: The extra padding layer is attached to the mattress, sitting flush with the edges. This offers excellent edge support, better motion isolation and minimal shifting.
  • Appearance: Euro top mattresses have a sleek, streamlined aesthetic, which some users may prefer for their decor.

What’s the difference between a firm and a medium firm king size mattress?

A firm king size mattress tends to be sturdier, offering solid support with minimal sinking — a good fit for back or stomach sleepers. A medium firm mattress, meanwhile, strikes a balance between support and comfort, making it a suitable option for various sleep positions. It’s not as stiff as a firm mattress, but still retains the supportive qualities required for a good night’s sleep.

Because every sleeper is different, there’s no single king size mattress that we can call “the best.” Which king size mattress is best for you depends on your personal needs and preferences. For instance, if you’re a side sleeper, you’ll want to look at a plush or pillow top mattress for extra pressure relief. On the other hand, if you primarily sleep on your back, you may find that a firm mattress gives you optimal spinal alignment.
