Quick Summary
Costco’s Kirkland Signature sheets deliver premium materials and construction at roughly a third of the price of Brooklinen or Boll & Branch. The trade-offs? Fewer color choices, limited seasonal stock, and a slightly heavier sateen feel. But for the price, it’s hard to find a smoother, longer-lasting set.
My Personal Experience
I’ve rotated through Kirkland Signature, Brooklinen Luxe Sateen, and Boll & Branch Signature Hemmed over the past few years, alternating them seasonally. Here’s what stood out:
- Kirkland Signature: After a year of weekly washes, the 680TC Pima sheets still feel smooth with minimal pilling. They’re a touch heavier, which feels cozy in winter. Grip-On corners are a quiet hero—these things stay put.
- Brooklinen Luxe Sateen: I picked up the Luxe set during a sale. The drape and sheen are next-level. They wrinkle a bit more, but the silky feel makes up for it. They’re slightly warmer but look high-end. Here’s their latest pricing.
- Boll & Branch Signature Hemmed: The softest percale I’ve slept on. Breathable, crisp, and cool—the opposite of slick sateen. After two years, they’ve mellowed into that perfect “broken-in” hotel texture. The cost, though, stings.
If I had to assign them: Boll & Branch wins for comfort, Brooklinen for aesthetics, Costco for value.

Buying & Sales Notes
- Costco: Sales often appear during bedding season—expect 15–25% off in rotation.

Final Thoughts
If you want dependable, luxurious-feeling sheets without paying triple digits, Costco’s Kirkland set is a quiet powerhouse. They’re durable, soft, and carry that rare “sleep better tonight” factor. Brooklinen brings hotel-grade polish and brand cachet, while Boll & Branch is for those chasing ultimate softness and sustainability.
My current rotation: Boll & Branch in summer, Brooklinen Luxe for guests, and Costco’s Kirkland for everyday reliability. It’s a mix that nails comfort, quality, and cost across seasons.
Try Brooklinen Luxe Sateen Sheets if you want a more refined drape, or stick with Costco’s Kirkland if you just want premium sleep at a fraction of the price.
