I was wondering what i need to look for in a mattress for my crip and what will be best for my baby.
The crib I have is the Simplicity Ellis

Dose anybody else have this crib and what mattress did you get and how well did it fit in the crib????

As long as it's a new matress they are all pretty much the same size and will fit snugly in any crib. I personally got a Sealy one for around $100.

Edited to say: some matresses are not as thick as others but that won't prevent it from properly fitting snugly in the crib.

Yes, we have that crib and we got this mattress:

It fits perfectly and seems sturdy and wipeable.

any crib mattress will work....as long as you don't use a round mattress in a rectangular crib that is  

Quoting nurselisa_99:“ Yes, we have that crib and we got this mattress: http://www.target.com/Sealy-Natural-Rest-Mattress/ ... [snip!] ... It fits perfectly and seems sturdy and wipeable.”

Yeah that's the same one I have except with a grey flower pattern on the nylon "fabric" covering.

They all are pretty much the same. I got that crib in the dark cherry haha....did you have a problem getting a bumper that fit all the way around it? Mine is way too small and I was wondering if it was the crib or the bumper

My crib is still in the box   we dont know if we will be moving before the baby or not.
