A premium memory-foam carpet cushion that pairs plush 8 lb comfort with a real moisture barrier and pet protection, so it suits family living rooms and bedrooms rather than just filling space. It costs more than basic rebond and can be too soft for low-profile carpet, but it also extends Mohawk carpet warranties when matched to a qualifying carpet.
Pros
- Memory-foam feel with an 8 lb density gives plush comfort without going too soft for most carpet warranties
- Built-in moisture barrier with All Pet protection repels spills and pet accidents, good for family homes
- Green Label Plus certified with up to 90% recycled content, and it extends Mohawk carpet warranties
Cons
- Costs more than a plain rebond pad of the same thickness
- The plush 1/2 in profile can be too soft for some low-profile or Berber carpet specs, which call for 3/8 in
- The full warranty extension applies when paired with qualifying Mohawk carpet, not just any carpet

Frequently Asked Questions
- Can a memory foam pad still meet carpet specs?
- This one is built to. At 8 lb density it gives memory-foam comfort without going too soft for most carpet warranties, which is the usual failure of plush pads.
- Does the warranty extension apply to any carpet?
- No — the extension up to 20 years applies when paired with qualifying Mohawk carpet, not with just any carpet. Check the pairing before counting on it.
- Is 1/2 in too thick for some carpets?
- It can be. Low-profile and Berber specs often call for 3/8 in, which Mohawk also offers. Match the pad thickness to the carpet spec sheet rather than picking the plushest option.
