YOFIT Multipurpose Cargo Organizer Blocks Car Trunk Storage Organizer Blocks, Should Be Used with Wool Trunk's Carpet for Car/Truck/SUV/Van, Set of 4

These work great. I use them to hold my subwoofer in place in my trunk, so that the box doesn't slide around. Only thing is that you need fabric to get the velcro to work, so I had to take the weatherproof rubber lining out of the trunk in my case.

Really sticks to my car’s carpet. Holds heavy tire chains (case) in place. These are very useful and way to use. Very sturdy and well priced. Dealer’s price was double this.

Worked like a charm, maybe a little too well. They really attach to the floor of the cargo area, hard to pull up and move, my spouse complains…. Solved the problem.

When I purchased a SUV back in 2013, the vehicle came with a set of organizers identical to these. I am not exaggerating when I say it might have been the best feature of the car. The velcro bottoms of these strorage blocks adhere tightly to the carpeted cargo area. You can't use these, unfortunately, if you have a rubber trunk liner as there is nowhere for the velcro to stick.By strategically placing these blocks around what you are transporting things just don't slide around.I have bought a few sets of these blocks for other cars I have owned and don't know why they don't come standard in all SUV's.

The description is inaccurate. This product might be stable if your trunk has carpet material since this storage product has a Velcro like side to it. But my car has rubber not carpet so that could be why this product didn’t work for me.I did a test run on this and it failed the test. For starters there are no instructions to put this together but once you figure it out it’s easy. However, rearranging the pieces can be a challenge at first try bc the pieces get stuck together pretty tight, you’d have to use something to pull them apart to reattach them. Being how strong they seemed to attach to each other I thought they’d hold everything in place so, I tried testing it in the trunk space of my SUV and all of the items that I placed in this storage did not stay put. the entire storage shifted and let out all of my belongings (so nothing stood in place including the storage unit). The odd thing is that there are 4 corners that you create by attaching 2 pieces together yet you cannot attach the entire thing together. Hard to explain but the way this was designed doesn’t make sense for functionality for me, so I returned it.

I bought these to hold a Vera Bradley carryall, a gift when I bought my new car, in place in my car. The mat in the cargo area is two-sided so I have the carpet side up. These hold the carryall in place perfectly. I use the extra pair to hold things like my recycle bin, boxes of wine, jugs of kitty litter in place depending on what is needed. They do a great job.

Very sturdy, sticks very well to my wool type trunk mat. I like that it can be changed but since I travel a lot, having a small space for my computer bag, and one for my common piece of luggage, I don't plan on moving them much. I was concerned over comments on not sticking and suggest a potential buyer ensure that their trunk mat feels like the fuzzy 'loop' side of Velcro as the strips on the bottom of these is like the 'hook' side of Velcro.

Having a professional car service, there are items that we carry on board in our SUVs, one being a small ice chest, fire extinguisher, and step stool for our seniors.These sets were replacing elongated L-shaped thin plastic that securely held our ice chest in place at the bottom (with the handle secured onto two hooks attached to stainless posts of headrest) that over time has suffered fractures and eventually broke in half after years of usage.Hard-molded plastic appears to be durable but unless you ARE attaching a secondary piece to form an L ("corner'), this product would be useless in securing as the actual contact area with your carpet is just over an inch. Also, once you have joined second piece to form an L, the product is definitely secure BUT keep in mind, that once you have joined two pieces to form a "corner", the way they clip together is SOOOO secure that I doubt you would be able to separate to form another orientation.The supplied Velcro-like material used is inferior as compared to my original set that I was forced to replace after years. These blocks are only about 1.25" wide which limits the actual area secured to the cargo area floor, which limits their ability to provide adequate security. As I was unable to find identical replacements (which had 4" x 10" of Velcro), to make these work for our needs, I had to remove the Velcro-like material using a belt sander. I replaced the now-sanded area with 10 lb grade Velcro, using Gorilla glue in addition to the factory glue on the Velcro product.All is working well but more work than what I would have liked just to get it to work.
