Review on 🛏️ DuraCasa Bed Risers: Maximize Under Bed Storage Capacity with Reinforced Heavy-Duty Design - Holds Over 2000 LBS! Ideal for Furniture, Desks, Sofas, and Chairs (6, Black 3 Inch Set of 6) by Anthony Woolley

Most king size beds will require you to have 6 of these beds and most come in sets of 4. So my options were a bit limited. They are strong enough to hold a bed on them. But I wasn't 100% sure if they would be ok if I was sitting on a riser on the corner of the bed with my full weight plus the weight of the bed. The plastic is thick and feels solid, but I guess that's the limit. I solved this problem by filling all 6 with cement. I used quick drying cement (not concrete. You want a thinner mix that fills all the nooks and crannies in the riser. Concrete is full of rocks that don't completely fill the interior.) It's available at any Home Depot / Loews / any other hardware store. You'll need about $10 to complete all 6. Installation took 20 minutes. Healed within 24 hours. And now my free ends held the elephant that stood on them. And I can be 100% sure they will never tear or collapse.
