I bought this pack because it was modular and I wasn't sure which size I wanted, so this was a great option to try different heights. I considered buying more expensive, more flashy options once I found the right fit, but in the end, I decided that because they're on the floor under a piece of furniture, nobody is even going to see them. I have them under my Ikea couch, and it turns out I only ended up using one 2" riser under each foot, so now I have an extra pair for a different project. Each 2" riser comes with a rubber base that goes under the riser (I'm assuming for traction on hard floors), a foam pad to put between the riser and the foot of the furniture. They stay well on carpet, although they are little hard to position right (I used that blue sticky tack to keep them in place for final positioning, because you have to lift the furniture to reposition). Once they're in place though, they are very sturdy and have no wobble at all, and although I didn't use them on hard floors, I am confident they would work well. Overall I was very satisfied with the results. They aren't the highest end items, but they do what they are meant to do, and they do it well. 10/10, would recommend.My wife and I are in our 60s and it is getting harder for us to get up off our very low sofa and love seat. So just as a test, I raised them up using 2x6's and we liked that height a lot better. Obviously this looked really ugly, so I searched on Amazon and I was surprised how many options there are. I ultimately settled on this set.The set is solidly made out of heavy duty plastic and I am confident they will last our lifetime. The black color makes them almost unnoticeable, and they look about as good as a product like this could look. Unlike what other reviewers have said, it does come with 8 rubber pads for the bottom and 8 soft foam pads for between the furniture leg and the riser. BTW, the box has little stickers pasted over them where it originally said 4 pads of each type, and now says 8 pads of each type. Obviously, the manufacturer listened to the review complaints.My only ding against the product is that my sofa has 5 legs! Yes, there is one extra leg in the very center; no one would know unless they looked under it with a flashlight. I understand this is not uncommon with high-quality sofas. So I actually needed 9 of these risers for my sofa and loveseat. I knew this before I ordered, but it appears no manufacturer sells single risers to add to a set. So I had to make one extra out of a 2x6 plus a 1/2 inch thick piece of plywood (since a 2x6 is only 1-1/2 inches thick, I needed an extra half-inch to match the 2-inch risers). It looks pretty cheesy but no one can see it under the sofa. I sure wish this company would sell sets of 1 or 2 risers to use in a case like this.I needed thes to level out our split king adjustable beds, My wife is old school, (pillowtop,) and I'm new school all the way. My mattress weighs approx. 100 lbs, I weigh 360 and my adjustable base probably weighs 150-200. These risers take it all and then some.Perfect bed risers but be careful as they stick out and you may forget and bump your toe.The risers are very sturdy and easy to stack. The straight profile is just what is needed to save inches in a dorm room. They came quickly and in good shape. I gave 4 stars because missing were the foam pads and anti-slip slides for the bottom. I had ordered another set once before and they were included.I sent a message to Utopia customer service. I did not want to return the product (as was suggested by Amazon), just have the missing parts sent. Within 20 minutes I had a response & apologies from the company. Utopia quickly offered to fix the situation. Very impressed by them and highly recommend not just for a good product but quick and helpful customer service.One came broken. All the others were fine and worked perfectly.works great, 1 was broken when it arrivedgood item.And I bought these to put under my couch so it would be a little higher for me and they work great. Then I realized that I couldn’t slide my couch so I bought 3 1/2 inch sliders to put underneath this and now all is great, my coach is higher and it slides out so I can clean behind it. I recommend these.I installed these weeks ago and they are great. Six in a box did the four outer casters of my metal bed frame as well as the two inner casters. No slip grippers attach on the tops as well as the bottoms, my bed hasn’t moved at all.Malgré certains commentaires que j'ai lu, j'ai tous les caoutchoucs qu'il faut pour les 8 morceaux.To raise the bed
