Input:
Question: Are the given dimensions for the top or the bottom of the baskets?  I need to know dimensions for the tops (since larger than bottoms).
Document: Ordered for sorting clothes. These are easy on the back to pick up since they are tall, and I ordered more to use as regular laundry baskets.
Great for sorting and make a perfect load. Like that it has labels but could use some more choices since there are 6 baskets and only "dark, colored and white"
I have a really small laundry room and ordered these to help keep our laundry organized and flowing smoothly. Each night, I gather and sort it into these baskets that I've labeled: darks, whites, jeans, towels, delicates, orange/reds. When a basket is full, I know it's time to do a load! This beats my old method...having large baskets sitting around in my bathroom!! haha
Seriously, I should have bought these sorting hampers YEARS ago! I have had a war with laundry ever since becoming a mom. There are constant piles of dirty laundry and clean laundry all over the place. Laundry-sorting became a nightmare with two small children running around mixing up the piles and it would turn into an all-day process. I ordered the sorting baskets to save my sanity, and let me tell you - THEY ARE WONDERFUL!
We've been using three of these for several years now. We line them up in our laundry room, put a different colored paper on the wall above each one - white paper, labeled "Whites"; blue paper, labeled "Heavies"; and a pink paper, labeled "Colors". That helps the children know which hamper to put their laundry in.When the dirt builds up on the bottom, we simply take them outside, hose them off, and let them dry in the sun.
They work for us and were defiantly on the more affordable side. I would like them to be a little larger, but I can live with them.
Came as a 6 pack and I only use 3, so I have spares if they ever need replacing.
I bought these because I seriously had to get organised in the laundry. I have 5 set up and when one is full I know its time to put a load on. They hold the perfect  amount for my front loader. Great price, much cheaper than in Australia.
These hampers have worked very well for me. It allows me to keep several wash types sorted in a small space, and carry them to the washer easily. The handles could be a little stronger, but that doesn't interfere with the primary purpose. If you have a very large washer, or need to carry your clothes to the laundromat, these may not work out as well. I find that they hold about one load for me.
The description says they attach to one another but the method of attachment is simply a lip that you set over the top of a basket's next door neighbor. It won't stay attached like that if you bump them or jostle them.The negative I see is that the handles are very thin and I don't think these would be very sturdy as far as toting heavy piles of laundry to your utility room.
Answer: The top is approximately 17"x10 1/2".  Perfect sir a small place
