It's best to find cribs made mostly of solid wood. The lower priced cribs most likely use pine, but its a soft wood and could scratch more easily. Be on the look out for MDF in the cribs, you want to avoid this if at all possible. The glue that binds the MDF together contains formaldehyde, which can cause sinus/allergies and worse off is a known probable human carcinogen. Make sure you visit these cribs in-store even if you order online because you won't notice how well it's built. Make sure you lift up the crib mattress to see how it holds the mattress. You want metal springs or wooden slats, but a lot of crib makers try to use MDF to get the price point lower.
My grandma has generously offered to purchase a crib for BW and I have decided to go with a mid range option. I went in-store and these are my choices for you to vote on. We are also going with white.
#1- Babi Italia Eastside Lifestyle Crib
I like the classic look that it has and the little details.
Room View#2- Babi Italia Classic Crib
This one has higher sides with lower front and middle with similar details.#3- Baby Cache Heritage Crib
This one has a lot of ornate details (look at the columns). I am just not sure if its too much, in-store they looked a bit over the top. The matching dresser was also quite large. Reminds me of more of a Victorian style. This is the top recommended mid-range crib from the book.
Also, FYI- Crib brands they don't recommend-
Delta (sold at target, BRU)
Dorel (sold as Jardine @ BRU)
DaVinci (made by Million Dollar Baby)
Baby Letto- They rated B's, but have soft pine and Graco is better compared to Davinci and baby letto
Storkcraft (sold as Dwell Studio at Target) They love mdf.
