I personally love IKEA. No, I am not a spokesperson, just a rabid IKEA shopper.
So here are some tips.
Get there early. I have been to IKEA stores that have been in business for years and it doesn't matter. The place will be a mad house every weekend. I like to go on Tuesday's. The store opens at 10 but the cafe opens at 9. I go at 9 and get the cheap breakfast. Its a decent meal for 1.99.
Take your catalog. The store is much bigger than you can imagine and if you have something specific in mind it will be easier to show the staff what you are looking for and you will be overwhelmed when you get there. I have gone many times to get something specific, get distracted and end leaving the place without the item I went there for.
Grab the little blue map when you first walk in along with the pencil. The map will help you and the pencil is there so you can write down item numbers (on the back of the map) because when you get to the basement everything is organized in a warehouse type fashion and set up by the item numbers.
You assemble everything. I have had decent luck. The instructions aren't bad but my complaint is there is no words. Its all pictures and I actually like to read. There is a phone number to help you if you get stuck but I have never had to call. At the customer service desk in the basement there is a spot where you can grab parts for free. I have a little stash at home because a few times I have had missing parts.
Like I said the store is huge. The top floor is set up with the displays. Mini living rooms and kitchen set ups. Everything in the displays are for sale and each will have a tag. This where you will get overwhelmed. You will be like wow look at this, or wow look at that! Its like all of a sudden you get a major case of ADD.
If the store is busy it can be exhausting and frustrating. My husband would rather put a fork in his eye that go shopping there. I personally do not care for the lay out of the store. It has a path and its basically one way. My husband said its like trying to leave a concert. One flow of traffic and people that stop dead in front of you. It is true and that is why I like going during the week. Less busy. So after you make your way through the top floor it is now lunch time. Go ahead and eat again at the cafe. It has a lot of healthy and good food choices. Then you make your way to the basement. Again, its like entering another store.
Down there is house goods and everything you can imagine. To be honest, by the time I make it to the basement, I am almost spent energy wise. When you get through all that, then you enter the warehouse portion and this where you will find the items you are looking for. This will be the bigger items like furniture. You will be amazed that the large coffee table you want comes in such a small brown box. Look at the item number on the box with what you wrote down.
There is a scratch and dent area by check out. There are some good buys in there. Some are just discontinued items, displays or ding and dents. You can talk the staff down a little on the prices. I have done this before. They are as-is non returnables though, so make sure what you buy is something you definitely want. Also IKEA does not take checks. Cash, credit or debit only. I learned the hard way on that one. They charge for bags. They are about .10 cents I think or you can buy one of their blue re useable IKEA bags. They are maybe .50 cents. Can't remember now. I usually just take an IKEA bag or just don't bag at all.
The furniture is decent and IMO as long as it lasts me 7 yrs I am good. I like to redecorate and furniture usually goes out of style at 10 yrs anyway. I have made some great purchases and then some bad ones. It depends. I have two dressers. They are both sturdy. I have no issues with the bottom dropping out in the drawers. I have a teenager that stuffs his dresser more than he should so I can contest if he hasnt knocked out the bottom, no one will.
The beds are sturdy. I have bought two. I have not bought IKEA mattresses though so I can not say much about that. I have bought several desks and office chairs. The office chairs I bought sucked and were a waste of money. I also did not care for the small tv stand and coffee table we purchased. The tv stand bows and the coffee table was very complex during assembly. It has a glass top that slips and well it just wasnt a good buy. I love my billy bookcases and all the organizational boxes I bought. So I have had good experiences with the quality. Do I think the stuff will last me 20 years? Probably not but then again I don't beat the hell out of my stuff either. BUT the stuff does not move well. I agree with others on this. We have moved 3 times. My bookshelves did just fine but I wrapped them with shrink wrap. The desk I bought my son got pretty loose. I did tighten it but it got nicked up. The black brown furniture will show dings if you move it around a lot. I bought a furniture marker to help with this. But I can really expect a 69 dollar desk to hold up during 3 moves? No
Have fun.
Wear good sneakers! Its a fun store and you wont leave the place without buying something including the cinnabons at check out. The smell will lure you.
