Nursery decor help!

So we bought our glider and picked the color to match the crib we were planning on buying. Then last night my friend offered us a free hardly ever used crib which I’m more than thankful for, but I also don’t know how to make it match or look good with that glider one we already purchased. So here’s some pictures, any ideas? I’m thinking a dark grey mattress sheet to match the gliders fabric, and a white pillow for the glider to match the white crib lol.
