Utopia Bedding Bed Risers 3 Inch - 8 Pack - Round Furniture Risers with Top Anti-Slip Foam with Metal Plate & Bottom Rubber Pads - Bed Risers Heavy Duty for Sofa, Couch & Chair Lifts (Black)

I installed these under a bed for an elderly person and it raised the bed as expected and is stable. The risers were the perfect size both in height and width and the bed is now 3 inches taller.

Brilliant piece of equipment, just right to higher my bed a few inches. Larger than expected, they're like an upturned flowerpot. My bed, metal framed, has 9 legs, but there are only 8 of these, so I had to put something under the 9th leg. This actually isn't too much of a problem, because it's the (head end) middle leg, so carries less weight than the others. I didn't really want to buy 16 to use 9 lol. Anyway, they're good and strong, they work great, are easy to 'install', a fair price and came earlier than expected. Overall highly recommended.

They do the job securely but have a pretty large footprint

Did a great job of raising and supporting new bed to comfortably accommodate a senior couple with knee challenges.

They fit our out door wicker furniture perfect
