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.
Very soft, but not supportive. Owners agree that this mattress topper is very soft; many reviews compare it to sleeping on a cloud. That's great for some, but not everyone. Although many users say this pad relieves pain in their back and hips, others complain that the too-soft foam actually worsens their pain. Several posts add that their hips and glutes tend to sink into the soft foam, leaving their head and legs slightly raised. 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 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. A bigger problem is that this mattress pad doesn't come with a cover and tends to run a bit small, and the foam can snag and tear. Its thickness may also necessitate replacing your sheets with deep-pocket ones, although one user says she simply tucks the topper into the fitted sheet and leaves the mattress uncovered.
Watch out for sagging. Reviewers' biggest complaint about this mattress topper is that the foam tends to compress over time, developing a permanent indentation where the sleeper usually lies within a few months. Owners say this makes the pad much less comfortable and harder to move around on. Some find that it still works okay at this point, but others say the compressed foam causes back pain. The mattress topper has a three-year warranty. One user was able to submit a claim and receive a replacement, but considerable paperwork is involved.
