(4 customer reviews)

The Foam Shop’s Knee Bolsters are designed to comfortably float your legs to a higher elevation. Elevating your legs in this manner relaxes the tension in your lower back and allows your spine to lay flat and straight on the mattress. This greatly relieves any pressure or discomfort you are feeling in that area. Coming in a variety of bolster heights, you are sure to be able to find the right comfort fit for your body. Our Knee Bolsters come with a fitted zippered polycotton cover, removable for washing.

For pricing, availability and custom solutions, visit or call your local Foam Shop location.

Proper Positioning

The Knee Bolster is designed to be used on your back, with your legs curled over the top of the bolster. Your heels should then hover close to the surface of the mattress, but not rest on the mattress.

  1. Jason H.

    7 days of great sleep (so far)
    I sprained my back and I was having trouble sleeping. My physio recommended one of these bolsters and WOW. Who knew just having your legs elevated could make such a big difference. Very comfortable. I may just keep it after I recover.

  2. Chris T.

    Helped a lot
    I don’t know how it works, but as soon as I put up my legs my back feels way better. Recommend.

  3. The Foam Shop

    Glad to hear it Chris!

    FYI – it works by relaxing the connection between your lower back and your leg muscles, which means less stress on your lower back!

    This would be great except for one major design flaw. The zipper is at the bottom back of the bolster where your bum/top of your thighs rest. If you wear thinner clothes to sleep, you can feel the zipper. I found it quite irritating as I have sensitive skin. When I tried the bolster in the store, there a plastic cover on it so I didn’t know the zipper was there in the back. It would have been better for the zipper to be in the front where your feet hang over as the zipper being at the bottom wouldn’t touch any part of your body. Frustrated that I wasted $77 on a bolster that isn’t comfortable for me to sleep with. Also, I wasn’t advised that there were options for the colour and fabric choice. I was sold the Poly-cotton white one and would rather have gotten the Arctic stretch cotton one but I guess I should have been more vocal about asking about if there were any options. My bad.
