Incorrect spelling, explanation: a common mistake made in the spelling of the word upholstery is to write it as upholstry, which lacks the -e letter. This form, however, is wrong and is probably the result of the pronunciation of the word upholstery, which indeed might suggest that there is no -e letter in the word. That refers to the speech only and when you spell the word, the only correct version is upholstery.
