Mixing some nice quality or stand-out pieces with some ikea basics is a good way to go in my opinion. Some of their stuff falls apart, some of it lasts forever-- but at least you wont be too upset if something gets ruined because you won't be out too much money. It is the absolute perfect store for young adults trying to furnish their first places.
Also they're innovative-- not everything they have is furniture-- they have storage solutions and cool ideas for organization and decorating. Their showrooms are inspirational and may give people ideas they'd never thought of before.
I would go to IKEA for their tarp plastic bags alone. We use those things ALL the time-- carrying firewood, laundry to the laundry room-- dropping shit off at goodwill and just leaving them with the bag-- because why not? They're only 59 cents.
They also mix a few decent quality items into their line-up. They have quite a few things made of all real wood and we have a leather sofa of theirs that was $3200.00- -that's not cheap for a sofa, but it has lasted us 5 years so far and still looks great. I'm actually thinking of buying their Karlstad tufted leather sofa next, which is $1800.00.
Their appliances are nice and stylish. All of them are whirlpool and just have a small IKEA logo on them somewhere you can't see. They also aren't cheap. I put all IKEA appliances into my condo. Dishwasher: $650.00, microwave: $650, range hood: $1200, oven: $899, cooktop: $650-- we mixed them with a Viking beverage refrigerator and refrigerator drawers and it all blends nicely.
This was more of a response to the thread than your post, I kind of got off track a little.
