Mostly waterproof, yes. Pretty stinking close to waterproof, yes. But 100%? Not quite.
We take certifications and claims like “100% waterproof” very seriously around here. While the Liner Set’s fabric (a 100% polyurethane layer for waterproofing and a 100% polyester grey top layer for durability) is 100% waterproof, the zippers and seams that bring together the Liner Sets are not fully waterproof. To keep spills from seeping through the zippers, we designed zipper flaps that minimize the risk of water soaking through, and in our own product testing, we found that when used correctly, foam protected by a Nugget Liner Set remained dry, even hours after a major spill.
Watch this video for help! Quick pro tip: To maximize foam protection, it's best to orient the zippers of the base and cushion outwards and flap down.

Great question! Liner Sets come with six pieces in total: two for the thicker bases, two for the thinner cushions, and one for each of the two triangle pillows. Each liner piece is labeled clearly for easy assembly.
No. Liner Sets are designed and tested to protect Nugget foam — they aren't meant to be displayed or used during play. Because of the material used for waterproofing, Liner Sets are much smoother than Cover Sets and should not be used as a substitute for Cover Sets during play.
