Great for work at home!

I try to use this daily for 10 minutes using the middle placement of the removable slat. Build yourself up to it because it can be a very intense and sometimes uncomfortable stretch; I sit at a desk all day and need something to keep my back and hips from tightening up so badly. This works well and despite my thoughts about it being gimmicky I think over time it's helped to keep my back looser and more limber.

Great for back and shoulder pain. Worth every penny!

I can’t recommend this enough. I sit at my desk all day and my upper back and shoulders were hurting. Been using this for about 3 weeks and the stretch it gives you is amazing. Also, I use it while working on the chair and I feel a difference. I would highly recommend it.

This actually works like magic and instantly!

Wow I mean big wow! I've been suffering from chronic back pain for years and I've been to my physical therapist countless times. Before I bought this I aggravated my back 2 days prior to receiving this back stretcher and can hardly walk due to nerve-wracking pain in my lower back. My 2 lower disc is totally in bad shape. The first 10 minutes I used it I can feel the pain gradually going away and it feels so good laying down on it. The pain went away and I was able to walk upright again. I highly recommend this back stretcher.

So far so good!

I have just had it a couple of days but I’ve already felt relief. It arrived on time as described. A bit difficult to adjust the 2nd and 3rd levels. It might be helpful to include instructions about the correct placement.

Really relieves back pressure.

I was somewhat skeptical in trying these, but have had a few people recommend them.
I work and sit at a computer all day long. This is the perfect thing to have and use in the middle of the day and after work. It provides a great stretch and really relieves pressure.
This is also great for before and after long bike rides to stretch out my back and make sure I'm not sore the day after.

Useful for stretching and back pain.

Now that I work from home, I experience back pain much more often than before. I purchased this for my family and for myself to be able to stretch after a long period of sitting down. It seems to work especially since it helps with the lower back/lumbar area. It's like doing yoga but much more beginner-friendly.

I would highly suggest to friends.

Ever since this pandemic started I have been feeling anxious and stressed. I'm an ICU nurse and this definitely helps me release some stress that I have after a long shift.
