I bought them about....hmmm, maybe, Yikes! Ten years ago....which explains why when you sit down, you need a good set of climbers tools to get out. I know you're probably thinking I'm exaggerating. Take my word, I'm not.
I think it's probably easier to drop to your knees and roll to the closest, stablest piece of furniture, grab on and pull yourself up. I've done it, don't laugh! There is the option of grabbing on to someone standing nearby but keep in mind, if that someone isn't firmly planted with heels dug in, the two of you could end up in the abyss, lost for all eternity.
There certainly isn't the same traffic (meaning people) going through my house as there once was, but my house is lived in. The thing is, if you're not careful you could end up living in my sofa surviving off popcorn and chips for the rest of your life. If that sounds bleak, not to worry, there is the periodic rubber band or TV control that go missing and to feed your daily mineral needs dimes seem to get sucked in by the dozen.
I tried pulling the cushions out the other day to see if my daughters ring had fallen in (along with everything else); I nearly had to disassemble the entire sofa to remove them. The wires from the box spring (if that's what it's called) were sticking out through the material and were holding the cushions captive. It was similar to when you get your hair tangled up in a round brush while blowing drying; a rat's nest is easier to decipher. After a good long wrestle a Rock Star, cup of coffee and overdose of vitamins I was able to pull those suckers out. I still have the bruises on my forearms, if you don't believe me.
