DeepRoller PU90
For the spot a tennis ball keeps rolling away from.
The firmest surface of the three, 90 mm across and 200 mm long. Short enough to wedge behind your neck or lower back and stay put, which is the thing a ball won’t do.

Add to cart — DeepRoller PU90, $80Before you decide
Is the PU90 the one?
Three models, and the wrong one is the one that goes back in the closet. Here is who this one suits, and who it doesn’t.
Likely yours if
- Your day is mostly a screen, and by evening you notice the back of your neck and the space between your shoulder blades.
- You have tried a tennis or lacrosse ball against the wall and spent more time chasing it than using it.
- You want one roller that can live at the desk, on the sofa and in a weekend bag.
Probably not, if
- At 200 mm it’s short. Balancing a whole back along it’s awkward, and buyers say so. For lying along the full length of your back, the PU95 is the one.
- It’s the firmest material of the three. If firm pressure is new to you, start with less of your weight on it, or start with the PU95.
Still between two? Three questions name one model, with no email.
The object
A gap where the middle of your back goes.
A straight cylinder rests on the ridge of bone down the center of the back. This one is shaped so that ridge passes between the raised sections, and those sections take the weight instead. Separately, one invention in this line is granted as a patent in four countries. A patent reflects an examination for novelty and inventive step, not a finding about what the product does for anyone.

The ridges either side of the center, up close. 
Measured, not described: Shore A 63.5.
Four places to put it
Where it goes, and how far to move.
Four of the seventeen movements in the PU90 manual, filmed as they are written. The full set comes with the roller.
Upper back
Lie back over it with hands behind the head, hips on the floor. Move a couple of inches, breathe out, then move again.
Neck
Set it under the base of the skull and let the head rest on it. Turn slowly left and right rather than rolling up and down.
Glutes
Sit on it with one ankle crossed over the opposite knee, hands behind you for weight. Small circles, one side at a time.
Hamstring and calf
Sit with both legs out and the roller under the back of the thigh. Lift at the hands and travel slowly down toward the knee.
Go lighter than feels necessary on the first try. Most people who give up on rolling gave up after starting too hard.
Hand, and roller
The same place, without the appointment.
On the left, a therapist’s hand. On the right, the roller at the same place. The shape exists so you can reach it on your own floor — that is a statement about position, and we are not claiming anything beyond it.

What buyers wrote
In their words, drawbacks included.
7 of the 134 reviews of the PU90 in our Korean archive. How we chose them
Chosen by us, written by people who ordered through the platform named on each card. Korean reviews are translated by us; Kickstarter backers are quoted in their own words. Where we shortened one, the cut is marked […]. Buyers describe their own experience; yours may differ.
I already had an ordinary foam roller at home, so I hesitated. It is clearly different. Doing the same movement, the pressure feels much better. I will keep using it.
[…] Before this I used a tennis ball, but it kept moving out of place and felt a little too small. This is a good size and it does not slide, so it has become a favorite.
I bought it to take on trips. It is not heavy and it is small, so it seems good for traveling. Other rollers were too big to bring, so I always missed having one when I traveled. […]
I stretch on a regular foam roller almost every day. I spent a long time wondering why this one cost so much and why the reviews were so good. Very happy with it. Because it sits low, it works for the shoulder work I mostly do, and almost any angle is possible. […] Along the spine, honestly, being low and short makes it a little awkward. For the upper back, the front and back of the shoulders and under the arms, it is excellent.
I think it suits someone who wants something portable more than someone after whole-back or full-body rolling. The firmness is right, and it is very good on the neck and lower back, but lining it up for the legs and shoulder blades is a bit tricky. It does what it is for, so I am satisfied.
I like that it is light and does not slide. On car trips I never had anything good to put behind my neck or lower back, so I used a water bottle or a ball. Now it is the DeepRoller, and it is great. At home I also keep it behind my lower back on the sofa.
It looked too expensive and too short, and I went back and forth for a long time. I bought two anyway, one for my mother and one for me. It really is small. But when I decided it would not do and went back to the foam roller I already had, that feeling was not there. These days I only use this one. The thickness is right and so is the material. My mother uses it on her back, lower back and neck and has no complaint about the length. I mostly use it on my legs, so it is a bit awkward, but I expect I will get used to it. […]

Before you buy
You can have the guide first.
If a first try on a roller ever felt like too much, the guide starts lower than you would expect. It’s free, and it doesn’t come with a sales call.
The PU series guide
Seventeen movements from the official manual, each with where the roller goes, how far to lean in, and what should tell you to ease off. Then seven everyday situations — a screen day, a stiff morning, a long drive — with a short routine for each.

Feel is the rank you get from hardness against diameter, not hardness alone. PU65 is a softer material than PU90 and still the sharpest of the three, because 65 mm spreads your weight over far less surface.
The part we would rather not skip
Every reason we have heard for not buying.
“I already bought one of these and never used it.”
If you’re reading this, you may well own one already, and it probably cost less than this.
So the question isn’t what a roller costs. It’s how many times you reached for the last one. We can’t know that number — you can, and it’s the only one that decides whether this is expensive.
“A hundred and twenty-five dollars. For a foam roller.”
It’s four times what a plain cylinder costs, and a plain cylinder does roll.
The PU95 is 11.8 in long and cut away through the middle, so your spine passes under the gap instead of taking your weight. That shape is the patented part, and it’s the reason this one costs what it does. If you only want something round to lie on, buy the cheap one. We’d rather say that than sell you the wrong roller.
See the registrations“They’re all the same anyway.”
On the surface, yes. They look alike and the listings read alike.
When the Korea Consumer Agency lab-tested twenty of them in 2024, firmness inside one material ran from 153 N to 441 N. The difference was there. What was missing were published numbers to compare. So ours are published.
Read the numbers“Last time it just hurt, so I stopped.”
It happens, and it’s not a discipline problem.
How much of your weight goes onto it’s something you set, not something the roller decides. The guide is built around starting lower than feels necessary. You can have it before you buy anything.
Get the guide“There are three. I don’t know which one I need.”
Three is enough to stall on, especially when the differences are millimeters.
Three questions, no email and no waiting. You get one model back rather than a catalog.
Answer the three“Where is the evidence this does anything?”
There isn’t a trial on this roller, and we’re not going to imply one by wording a sentence carefully.
What we can show you is what was measured: diameter, length, weight and Shore A for all three, published per model. The shape is registered as a patent in four countries, which describes the design and says nothing about results. It’s exercise equipment, not a medical device, and the guide lists who should skip it.
Read the contraindications“What if I don’t like it? Sending it back to Korea sounds expensive.”
Returns do travel back to Korea, and on an ordinary change of mind you pay that postage.
The window is 30 days from delivery, unused and in its original packaging. If it arrives damaged, faulty or not what you ordered, the return is on us and so is the replacement. We say which is which up front rather than letting you find out after you open a support ticket.
Warranty and returns in full“Ten days? I’m used to two-day shipping.”
It isn’t next-day, and pretending otherwise would just make the tracking email a disappointment.
It leaves within three business days and most orders land about ten days after payment. Duties are paid before it ships, so nothing is collected at your door and nothing is held at customs waiting for you to act. You get the tracking number the moment the label exists.
Shipping, in detail“I teach. Can I put this in front of clients?”
We can’t tell you it suits any particular client. You know their history and we don’t.
What we can hand you is the same set of numbers for every model, a guide of forty-three movements filmed by the person who designed the roller, and a written list of the conditions where it should be skipped. Wipe it down between people: the surface is the same material all the way through, not a cover over a core.
See the movement guide“It’s a gift. What if I pick the wrong one?”
Three sizes is exactly two more than a gift buyer wants to think about.
The three questions take about fifteen seconds and name one model, and the PU90 at $80 is the middle of the line for a reason. If it turns out to be the wrong size, the 30-day window covers an unused roller in its original box.
Answer the three“It ships from Korea. What happens if something goes wrong?”
It does ship from Korea, and that’s a real distance.
Duties and import taxes are paid before the parcel reaches you, so the price on the page is the price you pay. If something is wrong with what arrives, it gets replaced, and the cover runs a year from delivery.
“I can’t feel it before I buy it.”
True, and for something you press your own weight into, that’s a genuine loss.
One thousand and fifty-five people backed the Travel Roller on Kickstarter before this US store opened. Buyers of the two larger models in Korea wrote down what it’s like to use, drawbacks included, and the movement videos show every position before you commit to one.

If it’s the one, it ships from Korea with the duties already settled. If you aren’t sure yet, the three questions are still there, and so is the guide.
