Large Capacity: Each underbed storage container has a large 45-liter capacity and measures 33"(L) x 17"(W) x 4.5" (H), making it ideal for storing various household items like clothes, bedding, pillows, blankets, jackets, off-season clothing, and toys. The container's compact 4.5" height allows for flexible use, as it can be easily stored under the bed, in closets, wardrobes, bedrooms, on shelves, or even under a sofa. These containers are perfect for simplified organization! Firm Sides and Bottom: Our underbed storage bags come equipped with honeycomb board on the sides and bottom, ensuring that they maintain their shape even when empty. This design makes our bags easier to push and pull under the bed than other products. Additionally, our bags feature a three-sided opening with two zipper locks, making it easy to put in or take out items.
