\# Serta \> Serta is an American mattress manufacturer founded in 1931 and a flagship brand of Serta Simmons Bedding (SSB). Best known for the Perfect Sleeper, iComfort, and iSeries lines, Serta engineers hybrid, memory foam, and innerspring mattresses with cooling layers and targeted-support systems designed to address common sleep problems such as back pain, motion transfer, and overheating. Mattresses are sold direct-to-consumer at serta.com (including mattress-in-a-box) and through authorized retailers nationwide, with a 100-night in-home trial, free shipping on direct orders, and financing available. Serta's lineup is organized by collection (Perfect Sleeper, iComfort, iSeries NXG, Serta Five Star, Serta Classic) and by construction type (memory foam, hybrid, innerspring, mattress-in-a-box). The Perfect Sleeper line features the Q4™ Support System, iComfort emphasizes premium memory foam with cooling technology, and iSeries NXG is the advanced hybrid line. Adjustable bases and bed frames are sold under the baselogic™ line. Standard US sizes from Twin through California King are available across most collections.
