Introduced in 1925 by Simmons Bedding Company, the Simmons Beautyrest mattress range has set the tone for mattress makers worldwide. Simmons Beautyrest mattresses use the company's patented Pocketed Coil technology. Pocketed Coil springs are individual springs wrapped in fabric pockets and attached at the middle. The design allows each coil to move separately, allowing for unparalleled motion separation. The benefits of this design were dramatically demonstrated in the Simmons Bedding Company's "bowling ball" line of advertisements, where a Simmons Beautyrest mattress with Pocketed Coil technology absorbs the impact of a bowling ball dropped onto it just inches from a filled glass of wine. The Simmons Beautyrest line comes in three ranges: The Beautyrest Classic collection includes two lines of heavy gauge Pocketed Coil springs for superior edge reinforcement, and memory foam in selected models. Each mattress has 800 pocketed coils springs. The Beautyrest World Class line features 980 pocketed coils, superior materials like latex and memory foam and Ultra 360 foam encasement for extra comfort all the way to the mattress edge. The Beautyrest Exceptionale line is the Simmons Bedding Company top of the range. It features a 1960 density Pocketed Coil mattress unit, the Simmons trademarked Two Story Coil-on-Coil construction and Ultra 360 foam encasement for superior sleeping comfort and luxurious nights.
