Our take on the So Sleepy 3" Latex Cooling Mattress Topper

The So Sleepy is a 3-inch mattress topper built in two layers: 1 inch of natural Talalay latex on top of 2 inches of ultra soft bio soy foam. The latex layer gives a buoyant, responsive feel and cuts motion transfer, while the foam layer adds plush pressure relief. A removable, machine-washable polyester blend cover with cooling-touch technology targets hot sleepers. Against memory foam toppers it breathes better and rebounds faster, but it is softer and less contouring than an all-latex topper.

Best forHot sleepers who want a cooler surfaceCouples bothered by motion transferBack and side sleepers wanting soft pressure reliefRenters or guests upgrading a firm or worn mattress
Pros

About the So Sleepy 3" Latex Cooling Mattress Topper

This 3-inch mattress topper is made for sleepers who run hot. It has 1 inch of natural Talalay latex over 2 inches of ultra soft bio soy foam. The latex gives responsive, buoyant support, and the foam adds plush pressure relief.

The cover is a soft, breathable polyester blend with cooling touch technology. It zips off and is machine washable. The latex reduces motion transfer, and the topper is made to promote spinal alignment and pressure point relief.

It ships compressed in a box and needs 24 to 48 hours to reach full height. A topper this thick changes how a mattress feels. It follows a sag in the mattress rather than fixing it.

Questions and answers

How firm is it?
It is on the soft side. The 2-inch bio soy foam base is plush, and the 1-inch latex layer adds bounce and support on top. It suits sleepers who find their mattress too firm, not those wanting extra firmness.
Does the cooling cover really help hot sleepers?
The cover uses cooling-touch fabric and the latex layer breathes better than memory foam. That helps, but the 2-inch foam base still traps some heat, so it is not a substitute for a true cooling mattress.
Can I wash the cover?
Yes. The zippered polyester blend cover is removable and machine-washable.
Will it fit my mattress?
It comes in Queen, Twin, Twin XL, Full, King and RV Queen (60 x 74). Match the topper to your mattress size.
How long until it reaches full height?
It ships compressed and boxed. Allow 24 to 48 hours after unboxing for it to expand to its full 3 inches.
How does it compare with a memory foam topper?
It sleeps cooler and rebounds faster, and the latex reduces motion transfer. Memory foam contours more and can feel firmer under pressure, while this topper is softer overall.
