51x16x4 in Heather Indigo Bench Cushion - Non Slip Memory Foam

In this review of the 51x16x4 in Heather Indigo bench cushion the bottom line is simple: this pad is for anyone who needs a thick, stay-put seat for an indoor or sheltered outdoor bench. The reviewer found the combination of the MIXFILLING memory foam and the LokGrip bottom delivers noticeable comfort and stability, while the FadeShield fabric keeps color looking fresh in sun-exposed areas. It is best used on dining benches, porch swings under an awning, and entryway seats where cushion density and non-slip performance matter most.

Key Features

• FadeShield fabric: solution-dyed polyolefin resists UV fading and retains color vibrancy even after heavy use.
• MixFilling foam: gel memory foam blended with high-density foam holds shape longer and provides supportive comfort for extended sitting.
• LokGrip non slip backing: spider web textured PVC bottom keeps the cushion securely in place with frequent use and movement.
• Double-layer bottom: a protective polyolefin layer inside guards the foam from friction and extends durability even if the outer grip layer wears.
• Water resistance: fabric repels most moisture with roughly 80% water resistance, suitable for covered outdoor benches.
• Easy care and recovery: ships compressed, fluffs back within 48 hours and cleans with mild soap and water for spot treatment.

Who It's For

The cushion is aimed at homeowners who want a thick, comfortable pad for a standard bench size and need it to stay in place on smooth surfaces like tile or hardwood. It suits front porch swings under an overhang, entryway benches, window seats and dining benches where a dense, supportive cushion improves daily comfort.

It is less suitable for fully exposed outdoor use in heavy rain since the fabric is water resistant but not waterproof, and those wanting a very soft, low-density cushion may prefer a different fill type. People who require machine-washable covers should also look elsewhere since care is spot clean only.
