large, nice, strong, baby love his stack when he was able to sit up we removed the arches so that it has more space to move. it is so big that we can settle it with him, which is nice .my son 10 years s' installs it to read. I wash machine and I even going to the dryer without problems, he always appears flawless only negative is not very thick, just when baby starts to sit up, he happens to fall and the carpet is not thick enough to absorb the shock at the head ... but it is so great we can safely add cushions to remedy this problem
