DS2 is currently still sleeping in his crib but he's been asking for a big bed recently, so it's time to move him out. He has a dust mite allergy so I need to get some encasement for the mattress and box spring. So a couple of questions.

- I know I need to get an encasement for the mattress. Do I need one for the box spring too?

- Do I need to get special pillows or just the pillow cover?

- Any recommendations on where to buy these items? Good brands to consider? I saw some on Bed Bath and Beyond's website but wasn't sure if they sold them in stores.

Am I missing anything else? Thanks!
