Put it down
Floor, mat, rug or bed. The base is flat and non-slip.
Acemend by Felmiro
Five minutes on your back. That's the whole routine.
You've tried the stretches you found online. You've bought the cushion, the belt, the roller. And every evening your lower back still feels like it spent the day carrying someone else's weight.
The Acemend Back Stretcher takes a different approach: instead of adding support, it opens space. You lie down on the arch, let gravity do the work, and your spine gently extends in the opposite direction it's been compressed in all day.
| 1 | Place it on the floor, a mat, or your bed. |
| 2 | Lie back with the arch under your lower back. |
| 3 | Breathe. Five minutes. Get up. |
No assembly. No batteries. No app. No straps to figure out. You take it out of the box and you know exactly what to do with it.
Start on the lowest setting if your back is stiff or sensitive. Move up as your mobility improves. Most people find level 1 plenty for the first two weeks — this is not a device you should force.
People who sit for a living. Drivers. Nurses and anyone on their feet all day. Anyone who's been told to "stretch more" without being told how.
An honest note: the first session will feel intense — that's normal, and it's why we ship with the lowest arch setting installed. If you have a diagnosed spinal condition, a recent injury, osteoporosis, or you're pregnant, talk to your doctor before using it. This is a wellness product, not a medical treatment.
Free shipping within the United States. Orders are processed in 1–2 business days and typically arrive within 3–7 business days. If it isn't for you, request a return within 30 days of delivery for a full refund — see our shipping and refund policies for full details.
One session a day. That's all this asks of you.

Anatomy
One moulded piece with no moving parts and nothing to replace.
A gap runs down the middle of the arch so your vertebrae sit in air, not on plastic. Pressure lands on the muscle either side instead of the bone.
Rounded, full-length ridges that follow the paraspinal muscles and stay in contact through the whole stretch.
Dozens of small pyramids covering the wider muscle sheet and the shoulder line — the part a round roller skips.
A reinforced curve rated to 260 lb on a flat non-slip base. Nothing to tighten, nothing to wear out.
Hover or tap any point on the product.
The routine
Nothing to learn, nothing to set up.
Floor, mat, rug or bed. The base is flat and non-slip.
Knees bent, arms comfortable. Let your weight down slowly — the arch does the work.
Roll off to one side rather than sitting straight up. Flip it under your neck for the shoulders.
Start on the lowest arch setting. Most people stay there for the first two weeks.
What buyers say
Working on stretching my back and increasing flexibility to resolve some poor posture issues from sitting at work too much. This definitely revealed how tight I am, as my shoulders do not reach the floor the way the image shows. But after using it every day I am almost there. It's a combination of increasing flexibility in certain muscles and strengthening the core. It's not easy but it actually feels good now, and my husband has started using it too. It's made well. Edit to update: it has been 1 month using it every day and I can now reach the floor with my shoulders. This item is useful!
Recommended product, reliable seller, high quality — it does exactly what it promises.
I was having a lot of lower back pain. This helped to ease that for me, in a big way. I go to the chiropractor regularly, and whenever I use this, they always say "you're moving really well today." I'm grateful that something so simple can make such a big difference.
This is a high quality product. I was afraid the foam would be too soft, but let me tell you, this thing is stiff. The peaks and ridges you see in the pictures are kind of soft, but not entirely — the whole thing is made of high density foam. It is very light, but very stiff and hard. I weigh just over 100 kg and when I lie down on it, it does not go flat at all. It holds its shape very well and gives a nice stretch. I bet they would ask 50 euros for this in a shop that specialises in back pain. Highly recommended.
This is surprisingly uncomfortable at first. I have found that it works best for me if I place it on the couch, bed, or thick carpeting — using it directly on our hardwood floor is not attainable for me. But it really does help stretch my back and relieves pain, enough that I can get relief to sleep. Make sure the thickest part is supporting your upper back and the narrow part is supporting your lower back. And don't give up: it really does help ease back pain. Next I'm going to try using it twice a day for 5–10 minutes like several comments have suggested.
Fast delivery. The item was properly packed, with no damage. There is no instruction sheet in the box, but a video can be viewed online.
I purchased this for my husband. He has horrible lower back pain that he can't seem to shake a lot of times, and after doing a little research we found this. Every time he feels even a slight bit of pain he grabs this. He even started using it when he works from home to give extra support on his lower back. This is definitely worth every penny.
Arrived quickly and without damage. I think it will help relieve my back after a tiring day. Thanks to the seller and the couriers.
I bought this in hopes of relieving lower back pain. It was stated that it may be uncomfortable to use in the beginning and it truly was. So much so that I wasn't sure that I could continue. But I was noticing a reduction in my lower back pain, which had been quite bad at the end of the day. After two weeks of use the device is not as uncomfortable and I'm still having good benefits from using it. My only complaint is that it came without any instructions, so you'll have to look them up online.
This is how it arrives. I recommend it.
As pictured, the ridges on this product are very prominent. They're very firm, and not very soft. However, it was a nice stretch on my back and released a lot of tension — exactly what I needed. The product feels high quality and nice and firm. I took off one star for the width: I believe the product would be nicer if it was wider.
It is okay.
Purchased several weeks ago and I use it once or twice a day for 5–10 minutes to stretch my spine. It seems to be helping. I use it on my bed, as it seemed like too much pressure while using it on my massage table.
This seems to work well for my daughter, who had some back tightness from working her first full-time job and standing on her feet more than she was used to. She also has one summer left of travel softball, so it is easy to pack with us and she can stretch between games.
I bought this as a gift for a friend of mine who has a bad back. She absolutely loves it. Others complained that the cushioning was uncomfortable but she said it's just fine. She's about 5'6" and the size is perfect for her. Well made and sturdy. Looks like it will last. For the money, it's unbelievable.
It provides a deep spinal stretch, helping to release tension and improve flexibility. While it offers relief from stiffness, its effectiveness will vary from person to person, and factors such as body type, posture and existing spine health influence the results. Overall it is a great tool for posture and mild discomfort, but do not expect instant relief for persistent pain.
I've been using this for a week now and my lower back does feel better, so I'd say it works. It's very hard, so if your back is sensitive you might have to use a towel or something soft until you get used to it. I recommend it.
It arrived on time. It's a little harder than I expected. Took a little time to get used to. Still working on it.
Kind of small. Great material. Does the job. I like it.
I have just got home, so I have not tried it yet. Appearance: very good. Very nice colours too, and it feels durable. I will recommend it.
The pillow looks high quality and good, and it is firm, which is what matters. Fast delivery. Thank you, seller.
Very helpful for back pain. Good product, and the same as the picture.
Good for lower back pain relief. I like it very much.
It took a bit long to arrive. It does the job it is meant to do.
I ordered the adjustable set because, for now, as a start to my exercises, this one is too high — but as back support while sitting it passes the test well.
The product matches the description. I recommend it.
Very good, I recommend the purchase.
Excellent, arrived quickly. Thanks to the seller.
Nice. I bought it for my mother's back pain.
Durable, and easy to carry and use.
Great product, good quality.
This helped me a lot!
Everything is fine, thank you very much.
Everything is great, thank you.
Exactly as in the photo.
Smaller than I thought.
A very good pillow!

Before you buy
Straight answers, including the ones that are not in our favour.
It will feel intense, and that is normal. It should feel like a strong stretch, never a sharp pain. Start with two or three minutes on the lowest setting.
Ask your doctor or physical therapist first. This is a wellness product, not a medical device. If you have a herniated disc, a recent injury, osteoporosis, spinal stenosis, or you are pregnant, clear it with a professional.
Once a day is plenty. Most people find the evening works best. More than that is not better.
Yes. Turn it around and place it under the base of your skull with your shoulders on the floor. Keep neck sessions to two or three minutes.
The frame is rated to 260 lb. Above that we would not recommend it — any flex changes the stretch it delivers.
Return it within 30 days of delivery for a full refund. You do not need to explain why.
