QWORK 4 pcs 6" Steel Tri-Dolly, 200 lbs Load Capacity, Great for Moving Furniture & Appliances, Durable and Easy to Use

These do the job but they have limitations. I moved a very large cabin bed/wardrobe/desk combined on them over carpet tiles using a pallet breaker/lever bar to lift the bed.If you try to sit the furniture on the rubber pads the whole thing tips sideways, you need to drop the furniture into the low centre channel to keep the castors on the ground.As you push/move the furniture the tiny wheels don't like going over bumps so you will need a lever bar just to take a bit of weight off the castor in question and it will happily pop over the bump.They swivel quite nicely but as you have to sit the furniture down into that central channel between the castors you can't push things flush up against skirting etc so you will need to hoof the last bit over with the bar hence why I recommend the pallet wrecking bar as it takes all the effort out of it.Overall, not bad. Can make 2/3/4 man lifts into a single person job as well as not damaging floors etc. Saves a lot of effort and your back

Disclaimer: I did not use these for their advertised purpose. My usage was a lot harder on the wheels than probably most buyers, using them in a workshop.I attached them to the bottom of a sofa bed, in order to move it to my house, from a Gumtree seller 5 minutes up the road. Didn't want to pay for a van to move it, so thought I'd get creative. It worked well for half the journey, then gradually the wheels started failing, bending off their brackets. This was likely due to the stress of uneven paving slabs, but I did go slowly and was careful.My point is, while these might be great if you're using them in a limited capacity, they aren't sturdy enough to get creative in the way I would've liked.

Pros: Nice strong frame Smooth running wheels Unique tripod designCons: Any bumps and the wheels immediately catch Grips on tripod don't hold the box in place Wheels are a bit too small Doesn't come with tool to lift boxTried to make our plastic box in the storage cupboard more manageable, but unfortunately found this to be more of a hinderence. We have a small notch where the bottom of the door meets the hallway and each time it catches, it slides the runners out of place and makes the job harder. Not recommended.

Really good value for money, these wheels have stood up to near constant use above their weight classification and are still working well. Much better than many of the furniture dolls I've used previously

The wheels turn well but I could not fit them in the small place I have unfortunately. This is the only reason why I returned it, else the actual quality is good and easy to use.
