Very soft, but not very supportive. Owners agree that Serta Ultimate 4-inch Memory Foam Mattress Topper is very soft; many reviews compare it to sleeping on a cloud. That's great for some, but not everyone. Some say they sank too far into this 4-inch memory topper, and felt as if they were sleeping on a giant sponge. However; the vast majority of users say it has transformed their old mattress and greatly improved their sleep, adding that it is soft yet supportive. The topper seems to be most popular with side sleepers, less so with stomach sleepers. Very few co-sleepers report "rolling" into each other due to dips in the middle. Like most memory foam mattress toppers, the Serta retains body heat to some degree, but most users don't find it bothersome and some say they appreciate the added warmth.
Odor disappears quickly. Like all memory foam mattress toppers, the Serta Ultimate 4-inch Memory Foam Mattress Topper has a chemical odor when new, but most reviewers find that the smell is minimal and disappears if the topper is aired out for a couple of days before use. The manufacturer suggests taking it out of the box and allowing it to unroll itself for 48 hours; this also gives any odors time to dissipate. However, many owners say the mattress pad was completely expanded and the odor gone in just a few hours. Some reviewers say that the Serta topper tends to run a bit smaller than the mattress they buy it for; although few report that as a problem, merely an observation.
Longer-than-customary warranty. Many owners who purchased the Serta Ultimate 4-inch Memory Foam Mattress Topper as a temporary solution for a sagging mattress report being very pleased at how long it kept its shape and support. We found very few complaints of compression, tearing, or other durability issues, although there were a few owners who said they accidentally tore chunks out of the mattress, or that it came with a chunk torn out; however, these are generally corner pieces that don't affect the performance of the memory foam topper. The Serta Ultimate is made from viscoelastic memory foam which is hypoallergenic and antibacterial. It comes with a long, three-year warranty.
