SpillMaster® Ultra is the world’s best carpet cushion. Made of patented Never Crush™ foam, it is engineered to give the soft luxurious comfort you want while providing the lasting support your carpet needs. Never Crush foam’s dense micro-cellular structure acts like tiny shock absorbers cushioning every step. Plus, its high-density construction provides the ideal support factor, which is the foam’s ability to support the weight of a person without crushing or bottoming out. It recovers from virtually all indentations made by heavy objects and extends your carpet’s new appearance and useful life. Warranted for a lifetime to the original purchaser, SpillMaster Ultra is guaranteed to maintain 90% of its thickness over the life of the home warranty. No other carpet cushion feels as good or will last as long. It also protects your home from moisture and mold, two of the biggest challenges for floors. Made of breathable water-proof foam, SpillMaster Ultra stops liquid spills while allowing moisture vapor trapped beneath to pass through the cushion and evaporate. This high-performance feature helps prevent stains and lingering odors, since spills can be easily cleaned and moisture isn’t trapped underneath the cushion where it might cause mildew or damage to your subfloor. It is important to realize that mold and mildew will grow on any material or surface where moisture is present. Beneath your carpet is an ideal place for microbial growth. However, SpillMaster Ultra with antimicrobial protection prevents the growth of harmful bacteria and microbes on your cushion. It also protects your home from moisture and mold, two of the biggest challenges for floors. SpillMaster Ultra is the only carpet cushion certified by UL Greenguard Gold for very low chemical emissions, it has virtually no odor and contains no harmful flame retardant chemicals. It is also Green Label Plus certified by the Carpet and Rug Institute.
