The pad under your carpet quietly decides how the floor feels underfoot and how long the carpet lasts, yet it is easy to over- or under-buy and even void your warranty. Rebond is the firm, cheap workhorse for basements and heavy traffic, memory foam adds plush comfort in bedrooms, and a premium moisture-barrier cushion pairs softness with pet and spill protection. We break down rebond versus foam by density, thickness, moisture protection and warranty fit so you buy the right cushion for the room instead of just grabbing the thickest one.
A workhorse 8 lb rebond carpet cushion firm enough for heavy traffic yet still cushioned and warranty-compliant, with an integrated SpillSafe barrier that blocks slab moisture in basements, made from recycled foam under $1/sq ft. It feels firmer than memory foam, is strictly a hidden underlayment, and the wrong density can void a carpet warranty.
- Basement
- High traffic
- Broadloom
Pros
- 8 lb density is the sweet spot: firm enough for heavy traffic yet still cushioned, and meets most carpet warranties
- Integrated SpillSafe moisture barrier blocks spills and slab moisture from soaking the pad, a basement must-have
- Made from recycled bonded foam (Nike Grind content), making it a low-cost, eco-minded choice at well under $1/sq ft
Cons
- Rebond feels firmer and less luxurious than memory foam or thick froth pads
- The multicolor bonded scrap look is fine hidden under carpet but is not a finished surface
- Too-thick or too-soft rebond voids some carpet warranties; you must match density and thickness to the carpet spec
A plush 1/2 in gel-infused memory-foam carpet pad that gives the softest, most cushioned feel of any common cushion, deadening footstep noise and insulating cold subfloors, ideal for bedrooms and low-traffic rooms. The softness costs durability: it bottoms out in traffic lanes, exceeds many carpet warranty limits, and wears faster than rebond.
- Bedrooms
- Comfort
- Living room
Pros
- Plush 1/2 in memory foam gives the softest, most cushioned feel underfoot of any common cushion
- Extra thickness helps deaden footstep noise and adds insulation over cold subfloors
- Ideal comfort upgrade for bedrooms and low-traffic living rooms where softness beats durability
Cons
- Memory foam compresses and bottoms out in high-traffic lanes, so it is a poor stairs or hallway choice
- 1/2 in thickness exceeds the max pad spec on many carpet warranties, risking a void
- Costs more than plain rebond for cushion that wears out faster under heavy use
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.
- Bedrooms
- Living room
- Pets
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
- What density carpet pad should I buy?
- For most homes, 6 to 8 lb density is the sweet spot. An 8 lb rebond is firm enough for stairs and heavy traffic while still cushioned, and it meets most residential carpet warranties. Bedrooms can go softer for comfort. Very low density feels great at first but breaks down fast under traffic.
- Can thicker padding void my carpet warranty?
- Yes. Most carpet makers cap pad thickness at 7/16 in to 1/2 in and set a minimum density. A pad that is too thick or too soft lets the carpet backing flex and delaminate, which voids the warranty. Always match the pad's density and thickness to the carpet manufacturer's spec, not just to comfort.
- Do I need a moisture-barrier pad for a basement or pets?
- It is strongly recommended. A pad with a built-in moisture barrier, like the Future Foam StepAhead rebond or Mohawk SmartCushion, blocks slab moisture from below and spills or pet accidents from above so they do not soak into the pad and grow odor and mold. It is close to essential over a concrete basement slab or in a pet home.
