Thank you for taking the time to contact Sears.
Actually, the description online is incorrect, 83102 should be Twin XL low profile foundation-Existence (measurements are 80" x 39" x 6.5"). There is no twin low profile foundation. Additional information, they where both Twin and Twin XL exist, the Twin XL is longer - 80" vs approximately 75" for the reg twin.
We apologize for the inconvenience.
