From inflatable backyard water parks to clever kitchen gadgets, Costco truly does cover almost every product category. But there is one area the popular warehouse does exceptionally well: home essentials, including bedding and sheet sets.
While bedding can definitely get a bit pricey, Costco's selection is pretty affordable (and not to mention, customer-loved!). Regardless of the style, size or material you're looking for, there are a number of soft sets available to shop online or in your local warehouse.
We rounded up the best Costco sheets right now (yes, one of its Kirkland Signature sets made the list). Click into each product to check prices for your preferred sheet set size and take your pick based on pattern, color, thread count and more.

With over 23,000 5-star reviews, Kirkland's signature king-size sheet set is a go-to bedding pick among Costco customers. Available in white, dark blue, gray and beige, the set includes a fitted sheet, flat sheet and four pillow cases. The fitted sheet even has grips that help keep the fabric from slipping off the corners of your bed. "The extra-thick elastic and design of the corners on the fitted sheet raises the bar for all other companies," raves one customer.
Material: Cotton Sateen | Colors: White, Light Blue, Gray, Beige, Dark Blue | Sizes: Full, Queen, King, California King, Split King, Split California King
This 100% cotton sheet set is highly rated for its breathability and soft texture. The included fitted sheet also comes labeled so you know which sides are the top and bottom when making the bed. Go for a classic white set, or opt for one of the other four colors.

Although they're a bit more expensive than some of the other bed sheets available at Costco, Highland Park's 1,000-thread count set is a hit among shoppers: "I've chased the perfect sheets forever. They need to be smooth without feeling like silk, they need to stay tight, and the sheets must just feel right. These do, and they do it in spades. So much so that after a month of sleeping on these, and washing them every 4-5 days, I have purchased two backup sets!"
Material: Polyester Microfiber | Patterns: Bombay, Dorian, Ernesto, Maisie | Sizes: Full, Twin XL
If you have a full or twin XL mattress, this patterned 4-piece set by South Point Home Fashions offers unbeatable value. "This set of sheets was at an exceptional low price in the warehouse and I decided to give it a try after I was able to touch and feel the material. So glad I did! The quality met the expectation of the price paid."
Material: Microfiber | Colors: White, Gray, Ivory, Blue, Green, Beige, Light Gray | Sizes: Twin, Full, Queen, King, Split King, California King
Regardless of the size you're looking to purchase, Costco offers a discounted rate on this sheet set when compared to the manufacturer's site. For example, while this twin set typically goes for $110 on JenniferAdams.com, Costco sells it for just under $70. Available in white, gray, ivory, blue, green, beige and light gray, there's a color choice for every bedroom style. With over 4,000 5-star reviews, customers praise this high-quality set.

Struggling to find a sheet set that fits the thickness of your mattress and mattress topper? The fitted sheet in this set fits mattresses up to 18" deep and comes with elastic all the way around so that it doesn't move in your sleep. "My mattress is a bit on the thicker side, but the fitted sheet still stretches well enough to cover it," says one customer.
