It features a high, box-stitched design with strong piped edges that create walls between the top and bottom layers of this comforter and prevents the polyester filling from clumping and shifting. Thanks to the box-stitch design of the Utopia comforter, you do not have to worry about the filling becoming clumped in one section.

 The Wake In Cloud Marble Comforter Set is a seriously good looking comforter. Most comforters out there do not come in attractive patterns – instead, they usually just come in white.

This attractive California king comforter utilizes a soft, 100% microfiber filling that is extremely durable, hypoallergenic, wrinkle-resistant, and fade-resistant. Another huge bonus with this comforter set is that it is machine washable, so you won’t have to worry about the hassle of taking it into the dry cleaners. Also, this is a three-piece set, so it comes with a California king comforter as well as two marble pillowcases for an added bonus. Finally, the comforter even comes with a 30-night trial, so if you don’t love it you can send it back.

What to Look For In Your Next California King Comforter

There are a few things that you want to consider when purchasing a quality California king comforter. Make sure to check out the following qualities of a comforter before purchasing:

  • Ease of cleaning: You may not think about it at first, but with the amount of time spent in bed, it is important that you are able to keep your comforter clean. Check the label to find out whether the comforter is machine-washable or if it will need to be dry-cleaned. 
  • The fill power: The fill power refers to the amount of space an ounce of down filling takes up. Typically, the fill power can be found listed on the packaging or in the comforter’s product description. The higher the fill power, the warmer a comforter will be because it means that more air gets trapped by the down feathers. We suggest a fill power of at least 600 to stay nice and cozy at night.
  • The construction: A better construction will mean that a comforter will last longer. We recommend a sewn-threw construction to ensure that the filling stays evenly distributed throughout the comforter.  
  • The thread count: The thread count of a comforter is similar to that of a bed sheet as it indicated the number of yarns within an inch of the fabric. A higher thread means finer yarns and a softer touch. More importantly, a higher thread count ensures that the fill will remain evenly inside the comforter and will not leak out through large gaps between yarns. 

Frequently Asked Questions

What is the difference between down and alternative down?

Down comforters are filled with the downy feathers that lie closest to the skin of either ducks or geese. These are small feathers that provide the birds with exceptional warmth during the winter. On the other hand, a down alternative is a filling that is designed to mimic the warmth and fluff of down. Down alternative typically consists of cotton fibers, cotton-polyester blend fibers, or gel fibers. 

Are down comforters better?

This all depends on your preferences. Down comforters are lighter-weight and provide better insulation than down alternative comforters. However, down alternative is far less expensive and these comforters are easier to clean and friendlier for allergy sufferers. If you decide to go with down, we suggest that you try to find ethically sourced down.
