SweetNight CoolNest vs. Siena Signature: Budget Foam Mattress Comparison
Tom’s Guide compared the 12-inch SweetNight CoolNest against the 10-inch Siena Signature to evaluate cooling and support for budget shoppers. Source testing indicated the medium-firm SweetNight provided superior hip and shoulder cushioning, making it the preferred choice for side sleepers at roughly $400 for a queen. Meanwhile, the firmer $329 Siena Signature better accommodated back and stomach sleepers while including an extended 180-night trial, though SweetNight regularly faces stock limitations in twin and California king sizes.
Final price, sales tax, shipping, and eligibility are determined by the merchant.

Source-based
The source reports the queen SweetNight CoolNest at $399.99 and describes a medium-firm feel with cushioning at the shoulders and hips, making it worth considering if you sleep on your side and want a cooling-focused foam mattress. The article's tester reports good temperature regulation, but the cited price is a regular sale price, not evidence of a limited-time discount.

Tom's Guide published a mattress care guide highlighting preventative habits against bed bugs following reports of sightings in public spaces. The guide recommends keeping luggage and worn clothing away from beds, washing sheets weekly in high heat, and vacuuming tufts and seams regularly. For added defense, the author suggests full mattress encasements, noting models like Amazon Basics starting from $33.99 on Amazon. However, the guide cautions that encasements and vacuums cannot fully eliminate established infestations, which typically require professional extermination.
