Review on Aspeike Adjustable Furniture Suitable Elevators by Tiarik Gonzalez

Appears to be very durable. I've added a photo of the bottom as it's not listed. It's full of those long pieces of plastic inside. They don't have great transverse strength, but they do resist compression. This should mean that they are much more reliable than some of the other options that tend to fail what you support. There is a lid that snaps onto the internal supports. On the left in the photo, the bottom cover is removed, on the right with. The whole thing has different sized spacers that fit into the outer case to make it different heights. I used the full 3.8 inches and that seems like a great solution. Rubber pads are tenacious so the bed doesn't slip. Impressed. Will be updated if I encounter a problem.
