Mainstays King Comforter Set vs Sasttie 7-Piece King Comforter Set

Buy the Mainstays if you want a plain white comforter and shams and already own sheets. Buy the Sasttie if you want one box to dress the whole bed, including sheets and pillowcases, in a reversible teal and lake blue. The Mainstays has the larger rating base (4.6 from about 3,550) and a recycled-polyester shell; the Sasttie rates 4.5 from about 922 and wins on piece count and color. Both are lightweight all-season polyester builds, so neither is a step up in durability.

  • Choose the Mainstays if you want a clean white comforter with two shams and you already have sheets that fit.
  • Choose the Sasttie if you want a complete king bed in a bag with sheets, pillowcases and shams in a two-tone blue.

Questions and answers

Which is better for a guest room?
The Sasttie, because it includes sheets and pillowcases, so you can make the bed without buying anything else. The Mainstays works if the room already has sheets.
Which feels softer?
Both use brushed microfiber and owners of each describe them as soft. The Mainstays shell includes recycled polyester; the Sasttie leans on box stitching for loft rather than a different fabric.
Which lasts longer?
Expect similar life. Both are polyester with polyester fill, and the Sasttie's box stitching helps stop fill from shifting over repeated washes. Wash both cold and dry low.
Is the Sasttie worth stepping up to over the Mainstays?
Yes if you need sheets and pillowcases, since it replaces a separate sheet purchase. No if you want plain white or already own matching king sheets.
Will either fit a deep mattress?
The Sasttie's fitted sheet is cut with deep pockets for thicker mattresses. The Mainstays set has no fitted sheet, so check your own sheet depth separately.
Are they warm enough for winter?
Both are all-season, lightweight builds. Hot sleepers will be fine; cold sleepers may want an extra blanket in winter.
