What’s it like sleeping on this mattress topper? It’s not supportive at all, though it’s not really designed to be. A down mattress topper is really intended to create an extra layer of luxurious comfort, which this does tremendously. I really can’t overstate the softness of this. I think elastic straps to keep it in place could be a great addition, though I haven’t found that this slides around much!How comfortable was the mattress topper on a scale of 1 to 10? 10!!!Nashia BakerNashia BakerNashia BakerCoyuchi Washable Wool Filled Mattress TopperUpsidesSoft blend between organic cotton and a wool-blend fillingAiry feelMachine washableDownsidesLess ideal for side sleepers who like a dense, plush feelSpecsMaterial: Shell: organic cotton; fill: NATIVA wool and plant-based battingThickness: N/ATrial period and warranty: N/AReviewer: Nashia Baker, senior commerce editorWhat was the setup like for this mattress topper?
