Allswell Down Alternative Mattress Topper vs Sonoro Kate Bamboo Mattress Topper

The Sonoro Kate is the better pick for most shoppers. It has a denser 900GSM fill, a bamboo cover built for hot sleepers, OEKO-TEX certification and a deep pocket that grips mattresses up to 21 inches. The Allswell is thinner at 2.5 inches but uses a cotton and TENCEL Lyocell cover and is machine washable, and owners rate it slightly higher. Pick the Allswell if you want a lighter, breathable cotton-blend layer and a simpler fit.

  • Choose the Allswell if you want a lighter 2.5-inch layer with a cotton and TENCEL Lyocell cover and the higher owner rating.
  • Choose the Sonoro Kate if you sleep hot, have a thick mattress, or want the denser fill and OEKO-TEX certification.

Questions and answers

Which is better for hot sleepers?
The Sonoro Kate. Its bamboo cover and micro-ventilation holes are designed to move heat and wick moisture. The Allswell's cotton and TENCEL blend breathes but makes no cooling claims.
Which one is thicker?
The Allswell at 2.5 inches versus 2 inches for the Sonoro Kate. The Sonoro Kate's 900GSM fill is denser, so it may feel plusher despite being thinner.
Will the Sonoro Kate fit a thick mattress?
Yes. Its deep-pocket skirt is made for mattresses 8 to 21 inches deep. The Allswell lists a standard Queen fit without a depth range.
Which lasts longer?
Both are machine washable down-alternative toppers with no long warranty. The Sonoro Kate's denser fill may hold loft longer, but neither brand offers a written warranty.
Is the Sonoro Kate worth stepping up to?
For hot sleepers or thick mattresses, yes. The denser fill, bamboo cover, certification and deep pocket are real upgrades. Choose the Allswell for a thicker, simpler cotton-blend layer.
