The Serta Ultimate 4-inch Memory Foam Mattress Topper is a good choice for those who prefer a very soft bed. Many users like the way they sink into the thick, dense foam, and say it's great for relieving pain in their back and joints. However, others complain that the topper is too soft to provide good support and makes it hard to move around. It comes in twin, full, queen, king and California king.
Very soft, but not 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 great improved their sleep and is soft yet supportive. It 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 for a couple of days before use. The manufacturer suggests taking it out of the box and allowing it to unroll itself for 48 ours; 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. This Serta mattress pad doesn't include a cover, but an optional cover is available for about $60. Some reviewers also say it tends to run a bit small; 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 which 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.
The Serta Memory Foam Mattress Topper is second on this list of seven top memory foam mattress toppers, with an owner satisfaction rating of 91 percent based on the input of more than 23,000 owners.
