ANNKUT Bed Risers 6 Inch Heavy Duty,Oversized Couch Risers, Extra Wide Furniture Risers for Sofa Table Desk Headboard Chair Lifting,Rectangle Risering Blocks Support 6000 lbs(4 Pack Black)

These worked great, not the most visually appealing, but still very sturdy and work perfectly. Used under my Lazy Boy recliner on carpet, size was perfect, were not heavy so easy to set up and I believe a great way to raise chair for a small amount of money.

They are strong and great quality.

Works well to add height and stability.

Would be better if it had the lip all the way around but these are really nice and work well. They are strong.

Perfect for raising my bed!!

Worked great for my couches. I can vac under my couches. They are a bit too high but oh well. It works for me. I have to make sure they are snug and aligned on all four corners. right at corners so my couches don't move. Works great. I bought the other smaller ones different brand and my couch kept slipping from side to side falling off. These have high ridges to inclose the couch in place. Because they are on carpet they don't move at all. They are a light plastic but thick enough to supports a wooden couch and a love seat. My couch has an L shaped foot so it was hard to find something that would curve with its shape these worked best.

Right height. Good stability under the couch feet. Easy to place. Non-slip.

Are they attractive? No, but they raise a chair enough for my roomba to clean underneath and I can remove them if guests come over. If you're looking for something similar definitely buy ones like these that have a flared bottom for stability, I tried ones that did not have the flared bottom and they fell over constantly!
