WisperCloud™ is an amorphous shape, thus, its dimensions will vary. However, the approximate dimensions are about 50-56 inches x 20-24 inches x 20-24 inches. As you sit on the product and it widens, the products gets shorter.
Additionally, when you lay on the WisperCloud™ it conforms to your body, making a crescent shape. This shape allows the cloud to hold much more surface area than it's standalone dimensions.
