Hey Tired Mama,Thank you for reaching out to us. We understand your concern. The mattresses are made smaller so as to fit inside the bed frame. If the bed frame and the mattress were made to be the same size, they wouldn't fit together. Instead of listing exact measurements, it has been found easier for consumers to make purchases based on the sizes that are generally provided. Therefore, this variance is not considered a defect in any way. Please let us know if you have any other questions.Thank you! Lucid. Beds for the Whole Family.

Hey Hi, To help fluff up the corners of the mattress we suggest using a blow dryer to warm up the memory foam and massaging it as needed. Thank you! Lucid. Beds for the Whole Family.
