While there are many beds and bed sheets available today, there are just some unusual sizes that are still around. You might wonder what sort of bed requires three-quarter bed sheets. These sheets are specially made for antique beds that have an oddly sized mattress, 48”x75”. However, many of the three-quarter beds are no longer in production. Most of the bigger companies consider them obsolete in the furniture market. But, you can still find these sheets available from Bed Linens Etc. At Bed Linens Etc., we carry Three Quarter Sheets in Extra Deep Pocket to fit mattress depths up to 22".
