Review on 🛏️ iPrimio Aluminum Bed Riser - 5 Inch Lift with Incredible Weight Capacity of 36,000 pounds (6 Pack). Safest and Sturdiest Couch, Bed, Desk Lift. Floor-Friendly Design. by Paula Pickett

These are SOLID bed frame risers. We tried all the plastic bottles, some cracked or just didn't feel safe. We have a VERY heavy bed and felt they were the only climbers who could handle the weight and any 'extra midnight movement'. But they have a fatal flaw. Our Roomba gets stuck at these 45 degrees. lower edge! And while he's under the bed, he makes a PITA to suck on Roomba. So, as usual, I decided to make "better" the topic. Luckily we still had those plastic risers. So I hollowed out the center of the riser with a drill bit, pushed the aluminum riser bar through the plastic riser and SCREWED! It fits perfectly and what the heck, it even looks good! 1 star off because I don't like Roomba. Otherwise this is a RELIABLE product.
