Before knowing about the secret of the Hilton mattress, first, you should know about the Garden Sleep System. A mattress that comes with the Garden Sleep System contains multiple air cylinders. These air cylinders work with non-electric valves, which control the air pressure to give you a comfortable sleep.
The Hilton uses these mattresses only for their Garden Inns as a patented product. It works with an adjustable bed with a custom dial to adjust the mattress firmness as softer or firmer.
