Mattress, box spring, sofa bed and other small furniture

Hi,
I am relocating for a job and would like to sell some furniture I own. Here is the list

1. Memory foam mattress and box spring from Ikea
   I bought this one about a year ago and it is still in very good condition. Original price was over $400. I am asking for $180 (obo). See the link from Ikea below

2. Sofa bed
   I barely use this and it still look pretty new
   Original price is $399. I am asking for $150 (obo)

3. Dining table and chairs
   Orignal price is $250. I am asking for $100(obo)

Additionally, there are some other small stuff (e.g. book shelves, small cabinet etc.). These are also for sell and they are reasonable price.
