Bed Lifts: blessing or curse?

I purchased bed lifts from my local Bed, Bath & Beyond this weekend in an attempt to organize my shoe addiction.
You see, I already have 2 "shoe unders" a flat plastic rectangular tub which holds all my summer flats and flippys, and now my shoebox tower was growing too high to handle in my closet- not to mention blocking the actual clothing that the closet was intended for.

So I got these bed lifts and decided to try them out.

My first concern of course was: can this hold the weight of the bed plus my own?
(You see, I have an this "obese girl" mentality, where I think I weigh about 700 pounds and might break everything I sit on. Which is why I never sit on people's laps. Not even Santa- no gifts for me)
My other concern was: can this withstand my raucous love making? (which also stems from the aforementioned obese girl mentality)

Well, each individual lift hold 300 pounds, so 4 x 300= 1200 pounds. Okay, that was reassuring.

I moved the bed and lifted each corner and carefully slid the bed lift under. I took a step back and looked and noticed the the bottom of the bed formed a slight curve, as if the bed was giving me a sneaky smile to say "Wait 'till ya' sit on me, fatty...I'm going to collapse!" . I checked again and noticed that I put the lifts at the wrong place. I put them on the bottom of the head and foot boards, instead of the bed frame. So I switched them and instantly noticed difference in sturdiness. I hopped on top and gave the bed a wiggle... so far so good.
The bed lifts were a great success in solving my shoe box problem. I was able to stack 3 shoe boxes on top of each other because of the added lift. It also solved the Wii attachment problem, because now my 2 guitars and drum set also slide beneath my bed.

When I got ready for bed that night, the bed lifts also served as a self esteem booster. I did a little Borat singing "king in the castle, king in the castle" because having your bed that high make it seem as if you are indeed a king looking over your kingdom or in my case, the slew of rejected shoes that were on the floor waiting to be tossed in the trash.

Here is where the problem lies: In order to get off the bed I have to slide down off of it, which can be fun. Not so much fun for my remote control which also slide down and off the bed, slamming into the floor 3 times this morning.
