It's a stinky mat, but...

If you leave it unrolled outside in the sun for a day or two, each side, the smell will go away.  Worth it to pay a low price for such a good thick mat.  This is a good product, just have some time for the stink to fade..

But for now, back to the drawing board on this one. I find it a bit rough on the feet after a few minutes of standing on this mat. It appears that the darker "pebbles" have the suction cups underneath them, but they should have made them softer. On the bright side, it'll encourage me waste less water. Since it's not comfortable to stand on for long, I find that I have been taking quicker showers. Therefore it'll lower my water bill. Not sure if that was the manufacturer's intention though. Now when I say uncomfortable, I don't mean it feels like walking on real pebbles. It's not THAT bad.

If I feel like taking a longer shower, I suppose I could wear water sandals, or perhaps lose some weight. I'll admit that it may just hurt my feet because I'm about 30 lbs overweight. It's possible that customers giving this 4 or 5 stars either waited longer before the mat softens up, or they're just really lightweights and don't feel the discomfort of the on their feet. I won't lose hope on my new Slip-X mat, I'll update this review if it softens up over time. My girlfriend mentioned that it felt like a foot massage at first, but she thought differently after about 5 minutes.

Some may not find it uncomfortable to stand on, but our previous mat was cheaper mat and had a similar pebble design that was much more comfortable. Problem was it just didn't look as cool as this one, and the suction cups didn't suck (bad thing in this case). With this new mat, the suction cups stick better. With moderate effort, you can still slide this mat around. I find that it only slides around with moderate effort, but stays in place fairly well when you don't want it to move. Our previous mat would always slide around when we didn't want it to.

I've had this mat for 3-4 days now and it still has that unpleasant rubber smell people are mentioning. I'm not talking about a new showerliner plastic smell, cause I can tolerate that smell.  I'll give it a few more days to "air out" and see how it goes.

Bottom line is this mat looks cool, makes the tub surface less slippery, and was very easy to install. It also does its job in preventing dirt from building up on the tub's surface. For that I will give it a passing grade of 3 stars.

I've had this inexpensive cargo mat for 8 weeks now and I'm satisfied with it.  While it didn't fit my Toyota Venza well, I was able to trim to an acceptable fit, and it does provide a skid-free and protective surface that I wanted.  The most troubling aspect was that upon delivery it strongly reeked an odor of a curing rubber smell -- rendering it unusable for almost two weeks, and requiring me to scrub it with detergent and air it out before placement in the cars cargo area.  I'm not favorable to manufacturers who know about a problem and yet they expect their customer's to deal with it; and I say that because I called the company who made this and they told me how to get rid of the odor.  For all that the best I can do is be kind and give this product 3 stars.

This is not odorless mat, it smells very bad inside the car, i had to clean this with dish liquid and dryup couple of days outside before i can actually use it.

This is cushy, thick, comfortable mat that I can use for Pilates exercise. I like the feel of the mat but wish it does not smell this bad. I leave it in my living room and it stinks up the whole living room! The smell is too strong I feel it is not healthy to inhale...

Update: after a couple months of use, the mat does not smell much. However, I noticed the mat stretches too much when I and doing some standing up exercises. It reduces my body stability and limits my movement. Next time when I buy an exercise mat, I would choose something thinner and harder than this item.

Thus I took one star from 4. Now it is 3.

Beautiful mat, much bigger than expected. Be aware there is a somewhat strong odor to it- smells a lot like yerba mate tea. May bother some people.

I bought his mat to go on a outside ramp that we built for our aging dog with leg/joint problems. It's been 6 weeks and there is still a horrible toxic smell from it..especially on a warm day. I would of thought the smell would of went away by now...but when I open the front door of my home.. I immediately have to close it or the smell will get in my  house..it is a good mat for what I needed it for..just hoping the smell will eventually go away.

I bought this as a cooling mat for my dog's Sherpa for when we fly but I will be returning it. It fits the Sherpa fine but has such a bad odor to it, I don't want my pup to lay on it for any amount of time. The smell is horrid so it is being returned. A few reviews mentioned the bad smell but not all did so I thought I would see just how bad it was. The one I got is bad. It is going back on Monday.

While the mats are excellent in structure, the chemical smell is so strong and they are over a year old.  I've tried everything to get the smell out, but nothing works.

The smell is really strong and the mat isn't non-slip. It keeps everything in. Once, a friend thrown up inside the tub. I had to remove it to wash the tub (and the mat). I bought it because the color fits my bathroom, but everyday when I see it, I feel really pissed. 3 months later, you can still smell the fabric. I don't know why I didn't return it.

Nice sized heavyweight mat, will eventually serve (no pun intended) its purpose, but the rubber smell is overwhelming.  I've had 3 sessions of soaking in vinegar and UV sunlight, and it's barely put a dent in the smell.  As soon as the smell dissipates, I'll start using the product.

This is the third InterDesign mat I've tried, hoping because it was red that it might not stink as bad as the other two I had.  I sent it back.  No luck--every InterDesign mat I've had simply REEKED of a noxious, chemical smell, no matter how much I washed it or treated it to bleach.  This red mat is admittedly the least noxious of all the three InterDesign mats I've tried, but it still does smell.  Stay away.  If you're looking for a non-smelly mat, check out Orka products.  They don't have as many cute designs...but there ARE some cute ones, and more importantly, THEY DON'T STINK!!!

It does serves its purpose of making the tub less slippery. That being said it does have an overwhelming plastic smell that does NOT go away. I've bleached it, washed it in my washing machine, let it soak in soap, nothing worked. I've read similar reviews but thought I'd try it anyway. I have a huge bathroom so I thought that would help with not being able to smell the chemical plastic odor. I was wrong. It's also pretty uncomfortable on my feet. I'm a barefoot kind of person anyway but this just doesn't work for me.

I held off writing this review hoping the smell would go away but it simply doesn't. I've had this mat for a few months now and it's faded a little but it's still very strong.

The only reason I'm keeping it is because I already threw away the plastic. I like the color, and the look but if you are sensitive to smell I'd definitely look for something else! Hope this helps. :)

On the positive side this bath mat feels very good under my feet.  The little cushions seam to massage my sore, aching feet and stimulate the flow of blood.  The suction cups also do a good job of keeping the mat secure.  Even on my slightly textured tub the suction cups grip well.

On the negative side this mat smells really, really bad.  I tried several remedies to remove the odor, but nothing seemed to help.  I tried soaking it for three hours in a solution of vinegar and water, but it didn't do a thing.  I tried soaking it in Epson Salt, dish-washing detergent, and finally I soaked it in Lavender scented bath oil.  I even let it air out for two weeks in my garage.  Nothing worked.  As soon as I put it in the enclosed space of the bathroom the air is filled with a heavy smell of plastic.  And the worst of all, whenever I touch the thing to remove it from the tub my hands pick up the horrible odor.

So no matter how good it feels on my feet, I cant use it because of the smell.

I am happy with this mat, at least so far. I like the look of it and it is just the right size. Also, the rubbery surface works good to hold me in place while I practice yoga. The main problem I'm having with it for now it that is has an unpleasant odor. That can be dealt with in various ways, sure, but it's a nuisance. I noticed that another reviewer commented that the material wore down over time; I can not comment on the mat's durability yet, as I have only started using it. But thus far my experience has been positive, apart from the smell.

Unfortunately, this yoga mat had a bad rubber smell.  Had to return it.  Liked the design and feel of the mat otherwise.....

I read several reviews before purchasing this floor covering and I am kicking myself for not paying attention. Several posters shared the smell that seems to fill any room this mat occupies. In the box came instructions stating there may be a smell but to lay it out flat before use and allow it to air out and if there is a smell to use a small amount of bleach and water. I have done everything I can to "wash" off the smell to no avail..so this is a mat that will be added to a landfill and lesson learned...pay attention to the reviews :-).
