Is this mattress worth $50.99?

Yes, if you need a mini crib mattress. That is near the bottom of its recent range, and GREENGUARD Gold certification plus a lifetime warranty are uncommon at this price.

Does it fit a standard full-size crib?

No. At 38 x 24 inches it fits mini cribs, portable cribs and some toddler beds. A full-size crib needs a 52 x 28 inch mattress.

Is the cover waterproof and washable?

The mattress has a waterproof barrier under the cotton cover, so it wipes clean. The cover is not removable for machine washing.

What is GREENGUARD Gold certification?

It means the mattress meets strict limits on volatile organic compound emissions, tested for use in nurseries and schools.

It is a firm foam mattress, as infant sleep guidance recommends. Some owners find 2 inches thin and add a pad.

Mini crib mattresses tend to dip during baby registry events and back-to-school sales. At $50.99 it is already near its low.
