Our take on the 4 Pack 1" x 18" x 18" Upholstery High Density Foam Cushion, Black | Replacement Square Cut Foam Padding for Seat Couch, Patio Furniture, Dining Benches, DIY Projects

This is a four-pack of square-cut upholstery foam pads, each 1 inch thick and 18 by 18 inches, in black. The foam is high density and firm, meant as replacement padding for seat cushions, benches, patio furniture or DIY work. At 1 inch thick it is a thin pad, so it suits light re-padding and topper layers rather than rebuilding a deep sofa seat. Shoppers cutting their own foam get four uniform squares to trim to size, which is simpler than shaping one large block.

Pros
  • Four uniform 18 x 18 inch squares per pack
  • Firm high-density foam holds its shape
  • Square cut trims easily to fit odd seats
  • Thin 1-inch profile suits light re-padding
  • Black color hides marks on exposed edges
Cons
  • 1 inch thick is too thin for deep sofa seats
  • Firm feel may be too hard for some sitters
  • No cover included, so fabric must be added
  • Cutting to size leaves offcuts and dust

Questions and answers

Is 1-inch foam thick enough for a couch seat?
Usually not for a main sofa seat, where 3 to 5 inches is typical. One inch works better as a topper over existing foam or for thin bench and chair pads.
Can I cut these to a smaller size?
Yes. The square cut and uniform density let you trim with a sharp knife or foam cutter. Cut slightly oversize and test the fit before final trimming.
Is this foam firm or soft?
It is described as high density with a firm feel. Expect supportive, fairly stiff padding rather than a plush sink-in cushion.
Do these come with covers?
No. They are bare foam pads, so you need to add your own fabric cover or slipcover.
Can I use them outdoors?
The foam suits patio furniture replacement, but bare foam soaks up water. Keep it under a cover or bring cushions inside when it rains.
What are the exact dimensions?
Each pad is 1 inch thick and 18 by 18 inches square, and the pack contains four.
