Who should buy which

Pick the PerformaSleep Hybrid Mattress, 12 inch Medium if

Buyers who want a 12 inch coil hybrid in a Medium feel delivered free to a contiguous US address, who will unbox and place it themselves on a flat base, and who are prepared to sleep on it for 30 nights before deciding on a return.

Skip if

You want a coil count, foam density or weight limit before buying, since none is published; you prefer a firmer feel, which PerformaSleep lists for its 2.0 and Essentials models; or you need a California King by a set date, since that size was out of stock with no restock date.

Pick the SweetNight CoolNest Hybrid Mattress if

Buyers who want a pocket-coil hybrid rather than all-foam and are working to a budget, especially anyone furnishing a guest room or a second bedroom where a $500 queen doing an honest job beats a $2,000 one.

Skip if

Skip it if you want natural latex or certified organic materials, if you are buying primarily on the cooling claim, which is unverified and the brand's own, or if you want the trial and warranty record of an established sleep specialist rather than a value manufacturer.
