Knee Pillow for Lower Back, Hip & Spinal Alignment Support

The MedCline Knee Pillow is a supportive lower-body pillow designed specifically for side sleepers who want to reduce pressure between the knees and improve alignment through the hips, pelvis, and lower back. Unlike using a standard pillow between the legs, this ergonomic knee pillow is shaped to stay in place and provide consistent support throughout the night.

It can be used on its own or as part of a MedCline Sleep System. Many customers pair it with the Side Sleeping Pillow and a MedCline Wedge as a lightweight alternative to a full body pillow setup.

Targeted Pressure Relief Between the Knees

The Knee Pillow is designed to gently cushion the space between the knees, helping reduce pressure points that can develop when the legs rest directly on top of each other during side sleeping. This support helps promote more natural hip positioning and can reduce strain that contributes to lower back discomfort.

How to Use the Knee Pillow

The Knee Pillow is designed to work in multiple setups depending on your sleep needs

  • Standalone use: Ideal for side sleepers looking to reduce lower back and hip pressure
  • With Side Sleeping Pillow: Creates a more complete head-to-knee alignment system
  • With MedCline Wedge: Supports side sleeping comfort while maintaining lower-body alignment
  • Travel-friendly setup: Compact alternative to body pillows for use away from home

Recommended Pairing: Side Sleeping Pillow for Lower Body Support

If using the Knee Pillow on its own or with a MedCline Wedge, we recommend pairing it with the MedCline Side Sleeping Pillow. This combination helps support both upper and lower body alignment by keeping the head, neck, hips, and knees in a more natural side sleeping position.

Frequently Asked Questions

What is the MedCline Knee Pillow used for?

The MedCline Knee Pillow is designed to be placed between the knees while side sleeping to help reduce pressure on the hips, lower back, and spine. It promotes more natural alignment by keeping the legs properly spaced throughout the night.

Why use a knee pillow when sleeping on your side?

When side sleeping, placing a pillow between the knees helps prevent the top leg from pulling the spine out of alignment. The Knee Pillow is designed to provide more consistent support than a standard pillow, helping reduce strain on the hips and lower back.

Is the Knee Pillow better than using a regular pillow between the knees?

Yes. While a regular pillow can be used between the knees, it often shifts, compresses, or loses support during the night. The MedCline Knee Pillow is ergonomically shaped to stay in place and provide more consistent lower-body alignment and pressure relief.

Does the Knee Pillow help with lower back pain?

The Knee Pillow is designed to support better spinal alignment during side sleeping, which may help reduce pressure on the lower back. By keeping the hips and knees properly aligned, it can help minimize strain that contributes to discomfort.

Can I use the Knee Pillow with other MedCline products?

Yes. The Knee Pillow is designed to work on its own or as part of a MedCline Sleep System. Many users pair it with the Side Sleeping Pillow and MedCline Wedge for full-body side sleeping support.

Is the Knee Pillow good for hip pain?

The Knee Pillow helps reduce pressure between the knees and supports more even hip alignment. This can be especially helpful for side sleepers who experience hip discomfort or pressure from direct knee contact during sleep.

Can I travel with the Knee Pillow?

Yes. The Knee Pillow is lightweight and compact, making it a convenient option for travel. Many customers use it with the Side Sleeping Pillow as a portable side sleeping setup away from home.

Do I need both the Knee Pillow and Side Sleeping Pillow?

You can use either product on its own, but many users prefer combining them for more complete alignment support. The Side Sleeping Pillow supports the head and neck, while the Knee Pillow supports the hips and lower body.

What are the dimensions of the Knee Pillow?

The MedCline Knee Pillow measures 10.5" × 7.5" × 8" and is designed with an ergonomic shape to fit comfortably between the knees.

Who should use a knee pillow for sleeping?

A knee pillow is ideal for side sleepers who want better hip, spine, and lower back alignment. It may be especially helpful for people who wake up with discomfort in the hips or lower back after sleeping on their side.

    Really helps

    I didn’t initially purchase the knee pillow in hopes that I’d adjust to the new wedge sleeping position. It didn’t really work

    Now, with the knee pillow, the body angle is more natural and easier to get and stay comfortable.

    Perfect fit!

    At first the pillow looked a little small but when I positioned it between my knees it was perfect and so comfortable! I use it along with my shoulder relief system when I sleep on the side where the short end of the body pillow is. Highly recommended!
