I struggle too & am not supposed to use a sling due to back problems. We don't clean much, don't bother putting away half the toys and generally have Very Low Standards. 
A treasure basket is great - search on here / google for more details.
A playpen or travel cot sometimes works (my DS doesn't like them much though). I do what I can during naps, or shut the kitchen door and let him maraud around, distracting him in a corner if I need to go in the oven (although he's not that fast yet).
Things like hanging up washing get done while he's around, and he marauds around the house while I wash up / tidy as necessary. If I really need to keep him out of the way I use the high chair for a short while.
Tweet, I spend most of my time at home doing chores and not playing with him, which does make me feel bad sometimes, but I do think it's important to share everyday life with them. I hang clothes / nappies on those small 'delicates' washing airers, and as a result they are one of DS's favourite toys, as he loves to copy what I'm doing. :)
Someone on a thread on here once said the worst is crawling up to age 2.5. So just a short while before it improves.
