Best King Orthopedic Mattress

Candace Osmond

Designed to offer pressure relief and ensure optimal support for your whole body, a king orthopedic mattress will make sure that your spine is properly aligned for pain-free sleep. These mattresses are ideal for people suffering from back pain, but can also be a great way to prevent chronic back pain from happening in the first place. Similarly, orthopedic mattresses make a good choice for anyone that is recovering from an injury or suffers from arthritis, osteoporosis, and similar conditions that require additional back and joint support.

A king orthopedic mattress is spacious enough for most couples and will suit anyone that prefers (or has to sleep on a) firm mattress. King orthopedic mattress can be made from memory foam, or boast an innerspring or hybrid design- as long as it is firm enough.

What Is an Orthopedic Mattress?

Many people get confused and overwhelmed by the sheer number of options on the mattress market: not only that there are different types of main designs, but there are thousands and thousands of interpretations of those designs. This can make the choice difficult to make, especially if you have a bad back or sleep in a position that requires a firmer surface for comfort. Experts recommend orthopedic mattresses in these cases, but while many mattresses tout this label, not all meet the standards needed to be called orthopedic.

An orthopedic mattress, to put it simply, is any mattress that is made with the sole purpose of supporting one’s joints, back, and overall body- hence the word orthopedic in the name. However, that leaves a lot of room for interpretation and many manufacturers slap on the word orthopedic to their product just because it loosely fits the bill, but that doesn’t mean that it is truly orthopedic. The matters are made worse because there are no certifications that could prove or disprove that a mattress is orthopedic- both in terms of design and the materials used.

So how do you know if a mattress is orthopedic? Orthopedic mattresses can come in all shapes or forms but they are always firm enough to ensure targeted support for your back and joints. So when you’re shopping for a king orthopedic mattress, don’t go for the label alone: be sure that the design fits the bill, rather than just a name.

Benefits of King Orthopedic Mattress

A king orthopedic mattress is any firm mattress designed for superior spinal support that measures 76 inches wide and 80 inches long. As such, it will comfortably fit two adults that want a spacious bed- or couples that share their bed with their kids or a pet. Firm and supportive, a king orthopedic mattress will be great for ensuring proper spinal alignment- but that’s not all you can expect when you start sleeping on one.

— Great for back pain

The number one advantage of orthopedic mattresses is that they can help prevent back pain- and relieve existing aches and sores. The firmness of a king orthopedic mattress makes sure that it provides the support needed for proper spinal alignment and healthy sleeping posture, which in turn eliminates the main reasons for back pain caused by an inadequate mattress. Combining pressure-relieving materials such as foam with firmness and sturdiness needed for back support, a king orthopedic mattress will make sure your joints and spine don’t ache when you wake up in the morning. And this goes for both sleepers- uniformity and even weight distribution make sure that each person gets tailored support and comfort.

— No motion transfer or rollover effect

For couples, motion transfer can be one of the biggest issues when choosing a mattress- especially if one person is a restless sleeper or gets up much earlier than the other. Mattresses that transfer motion will make you feel every little movement of your partner- most likely, this will significantly disrupt your sleep quality. A firm king orthopedic mattress will allow for no motion transfer- or very minimal transfer- which means that when your partner gets up for a glass of water in the middle of the night or tosses and turns trying to find a perfect sleeping position- you won’t feel a thing. The same goes for the roll together or rollover effect: you won’t be rolling over to your partner or the center of the mattress when you sleep on a firm, uniform sleeping surface such as a king orthopedic mattress.

— Comfortable for back and stomach sleepers

Firm mattresses are more suited to back and stomach sleepers: their sleeping position requires additional support for the body to retain a healthy sleeping posture. The mattress should prevent your hips from sinking in to promote proper spinal alignment, and that can only be achieved if the mattress is firm enough. On the other hand, side sleepers might find a king orthopedic mattress to be uncomfortable to sleep on due to its firmness. A compromise would be to go for a medium-firm option or buy a memory foam topper to go with your new mattress: the sturdiness and the firmness of the mattress will still offer benefits but the cradling effect of memory foam will help a side sleeper find greater comfort with their new mattress.

5. Best for Side Sleepers: Nod Hybrid by Tuft & Needle

SPECS:

  • Type: Hybrid
  • Profile:10”
  • Firmness: Medium firm

People that sleep on their side put direct pressure on their hips, shoulders, and back- and a mattress that’s too firm will only exacerbate their pain and discomfort, even if it’s touted as an orthopedic design.

The independently pocketed coils lie atop an inch of base foam for superior stability and sturdiness that adapts to your specific body type- the springs are followed by 2 inches of T and N adaptive foam on top to contour your body and relieve pressure from shoulders and hips, and an inch of slow recovery foam to reduce the bounciness effect.

SPECS:

  • Type: Hybrid
  • Profile: 12”
  • Firmness: Medium firm

An orthopedic mattress isn’t worth much to a hot sleeper if it will trap heat and make them sweat at night. In addition to being supportive and comfortable, a king orthopedic mattress should also be cooling to meet the needs of hot sleepers- and that’s precisely what this design offers. The “secret” is in the combination of materials that are engineered to help dissipate heat and keep the mattress temperature neutral.

The individually encased pocket springs will allow the air to circulate, whereas the layer of gel-infused foam makes sure that the heat is drawn away from the body and dissipated instead of trapped by comfort foam. To boot, the cover of the mattress is made from a cooling and breathable material- bamboo rayon- so this mattress is not just temperature neutral but also cool to the touch.

ProsCons
  • Gel-infused foam dissipates heat
  • Cooling bamboo knit cover
  • Allows air circulation
  • Supportive and sturdy
