Best Knee Pillow 2021

Last Updated: October 14, 2021

Knee pillows are pillows specifically made to fit between or underneath the knees. These pillows have the potential to increase a person’s comfort while sleeping by promoting optimal spinal alignment, pressure relief, and friction between the knees themselves. People with hip or back pain, pregnancy-related discomfort, restless legs syndrome, or side and back sleepers may especially benefit from using a knee pillow.

While it is possible, and perhaps comfortable, to use a regular pillow, they may not provide you with the correct firmness, height, or shape. Knee pillows have been specifically designed to offer the optimal support and comfort for their purpose. Being informed of some of the options available and factors to consider are important in making the best decision.

What Is A Knee Pillow

A knee pillow may not be the first thing that comes to mind when thinking about getting the best night’s sleep; however, for some people, the addition of a knee pillow can make all the difference.

What is a knee pillow

Knee pillows have the potential to increase a person’s comfort while sleeping by promoting optimal spinal alignment and pressure relief. People with hip or back pain, pregnancy-related discomfort, restless leg syndrome, or side and back sleepers may especially benefit from using a knee pillow.

While it can be comfortable to use a regular pillow underneath or between your knees, a specifically designed knee pillow may be far more effective. Regular pillows may not provide you with the correct firmness, height, or shape. Different manufacturers may be able to offer you the best-suited features for your individual needs - whether those be a health condition or sleeping habits.

Benefits Of A Knee Pillow

The purpose of a knee pillow is to, essentially, relieve pressure on backs, hips, and knees and may be beneficial to a number of people. Please note, however, that a knee pillow should not be used to treat an existing medical condition, whether it be persistent pain or injury, without consulting a doctor first.

Benefits of a knee pillow

Pain Relief

It has been shown✓ that the addition of a knee pillow under the knees for elderly people with hip fractures was associated with a reduction in pain compared to more invasive traction alignment techniques.

Pain can sometimes be caused or exacerbated by an incorrect sleeping position. People with back or hip pain might experience the necessary support and pressure relief using the best-suited knee pillow, which facilitates optimal spinal alignment.

Did you know?
Approximately 2.6 million people in the UK seek help for lower back pain✓ from their GP every year.

Similarly, knee pillows can also promote spinal alignment in side and back sleepers, relieving pressure from their hips and lower back. Side sleepers often find their upper leg puts weight on the lower leg, resulting in the hips shifting, pressure and pain. Back sleepers often find it beneficial to place a knee pillow underneath the knees. This promotes the natural curve of the spine and minimises pressure on the lower back.

Comfort

Knee pillows are also said to help with pregnancy-related discomfort. Pregnant mums-to-be may find getting a good night’s sleep difficult for several reasons, and a well-suited knee pillow may provide some added comfort and promote restful sleep.

Restless legs syndrome (RLS) is a common condition of the nervous system and causes the irresistible urge to move one’s legs. Those who suffer from restless legs syndrome may find that elevating the legs during sleep may help.

Did you know?
Restless legs syndrome is thought to affect up to 10% of people in the UK✓.

Knee Pillows: Considerations

There are several factors to consider when purchasing a knee pillow, and the best choice will ultimately come down to your body, individual needs, and preferences. Below are a few things to consider so that you can make the most well-informed decision.

Knee pillows considerations
  • Shape: Most knee pillows are designed so that they are contoured to fit between a person's legs easily. Knee pillows for side sleepers are usually made to sit between the thighs or between the calves. Back sleepers are more likely to use cylinder and wedge-shaped pillows to put underneath the knees.
  • Support: The amount of support a knee pillow can provide will be dependent on the thickness and firmness of the pillow. In general, the thicker, firmer pillows will offer the most support. Heavier individuals most likely need the most support, whereas lighter individuals may not need as much.
  • Pressure: The firmness and amount of support a knee pillow provides will determine how much pressure relief is possible. Pressure relief on the knees themselves, as well as the spine and hips, can be minimised with the correct knee pillow.
  • Quality of materials: Knee pillows are usually made of memory foam (same material as regular memory foam pillows or memory foam mattresses) known for providing good support and excellent pressure relief. High-density memory foam will generally be of a higher quality than low-density memory foam. The price may often reflect this.
  • Size: The size and weight of a knee pillow may be a consideration for those who travel. Knee pillows may vary in size, so be sure to check for dimensions and weight if you are purchasing online.
  • Temperature regulation: Memory foam is known to trap and retain heat, and most knee pillows are made of memory foam, so it may be worth checking the different cover options. Also, some covers are made of more breathable fabrics than others, which may be an important consideration if you are a hot sleeper. In addition, bedding such as regular cooling pillows or cooling mattress toppers may also be a good idea if you tend to overheat at night.
