The pad under your carpet decides how it feels and how long it lasts, yet it is easy to over- or under-buy. We break down rebond versus memory foam by density, thickness and warranty fit.
The workhorse carpet cushion: 8 lb rebond with a built-in moisture barrier that suits basements and high-traffic rooms while staying warranty-compliant and cheap.
- 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 luxury soft cushion for bedrooms and quiet rooms, trading long-term durability and warranty flexibility for a plush, quiet, insulating feel.
- 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

Frequently Asked Questions
- What density carpet pad should I buy?
- For most homes, 6-8 lb density at 7/16 in is the standard and satisfies most carpet warranties. Go 8 lb for high-traffic areas and stairs; save plush memory foam for low-traffic bedrooms.
- Can thicker padding void my carpet warranty?
- Yes. Many carpet makers cap pad thickness at 7/16 in and set a minimum density. A 1/2 in memory foam pad can exceed that spec, so always check the carpet's pad requirement before buying.
