where to buy furniture / team up for IKEA run (Granada)

Recently arrived in Granada to give our kids a year of immersion school. I'll be working for the same company back in the US that I've been with for a while. I've been using a standing desk over 5 years now, and I was hoping to just get a desktop and adjustable legs from IKEA to build a simple one, but I just found that they don't sell that stuff online.

Anyone know a place where I could buy a standing desk in Granada, or have one built cheaply (€250 or less)? Alternately anyone want to team up to rent a vehicle and make the 90-minute trip to IKEA Malaga?
