My room's small so this cot is a suitable bed for now. However, sitting too far on either end can make it "buckle" and fall. This has led me to being mindful of where I sit though as it's a safety concern for small pets passing underneath. Besides that, if you lay blankets on top, it can be pretty comfy. I am 5'6", about 175lb, and feel stable enough, plus there's room so my feet don't danglen. Item is simple to use i.e. open it up and place! Overall, space-saving: yes. Efficient: enough. Recommend? I would. If I could tell the company to make an alteration, it would be to make the "feet" (3 bars) have more of a locking mechanism to prohibit buckling. It's not "amazing" but it's handy and #worksforme

UPDATE: The adjustable end broke so now my head is essentially hanging low to the ground while the rest of me is centered & "stable". Had to take my 4 rating to a 3
