Everlasting Comfort Back Stretcher for Lower Lumbar Pain Relief - Adjustable Spine Decompressor, Lumbar Support with 88 Acupressure Nodes and Memory Foam Pad - Back Cracker

Many of us spend much of our day with our back in flexion or with the upper body leaning forward, such as when we slouch in a chair. This allows the abdominal muscles to relax, contract and become shorter over time pulling the upper body forward and increasing the stress on the lower back muscles to compensate.The purpose of this product is to put the back into extension, or increase the arch in the lower back. This creates a very significant stretch in the muscles around the core and is not very pleasant. However, the benefits may be seen later when you notice movements that used to hurt, don't hurt as bad or at all. I've been using this about 2 weeks, and pain that I used to feel in my left leg when bending forward is gone and my low back pain after long periods of standing is noticeably less. I try to use it at least once each day for one or two, two minute sessions.The arch setting is adjustable to 3 different positions. I suggest the lowest position to begin with. This puts the least stress on the back and allows the body to become familiar with the product. When this becomes easy then move to the middle position. It's not easy to do, but you will get the most benefit if you can relax and allow the shoulders and tailbone to sink toward the floor.As for sturdiness, the arch is made of a flexible plastic. I can feel it give when I first lay on it, but it seems to regain its shape when I get correctly positioned. I weigh only 170 pounds. I can't say how it would perform for someone who weighs 220.For comfort there is generous padding on the arch. The center has a cushioning strip of rubber for the backbone. There is also an additional cushion which can be placed on the arch. Both can be used or removed as desired.Expect this product to cause discomfort during use due to the stretching of the core muscles. This should quickly subside after you finish your session and the back returns to a normal position. If the pain continues for more than a few minutes, I would suggest discontinuing use of the product. It is great to stretch tight muscles, but may be counterproductive if there is some structural issue with the spine. If you have any doubts talk with a medical professional.

Stretches my back and has lowered my pain level. Comfortable.

Good product, helped me to minimize the pain on my back, good price and it’s easy to use.

Really working! I am 5.4 and I don’t need longer for the lower back and actually the whole spine. Updates: I have made 3 stars because it is not anatomically correct and I had pain. Also in order to get up from this you need to have strong belly muscles. I have bought restcloud one. It is more expensive, but correct and even the angle is bigger I don’t have pain anymore.

This back stretcher is great for my stiff back. Please ease into its use. It is a ‘hurts so good’ feeling. I seem to have much better range of motion and more energy after using it. I use the lowest setting now, but I hope to be able to adjust for more arch in the future.

The hard plastic frame has an asymmetrical top and bottom dimension width . One end is 8 1/8" wide and the other is 9 3/4" wide. The padded cover is designed to fit the 8 1/8" dimension width and will not stretch wide enough to to fit the 9 3/4" dimension width. The difference being 1 5/8" overall. To make this work I will need to cut the wider end down 9/16" on each side. Recommend the use of a 80 grit belt sander. Prep should include a 3/4" strip of masking tape on both sides to establish the final material removal limit.It boggles ones mind how the previous 3-4 thousand reviews missed this material discrepancy!

If you have ever had a stiff lower back this is for you. You have to start on the low setting, but moving it up one notch will really help.

Works fine
