3 inch thick High Density Blue Swirl or Copper Swirl Memory Foam

Thank you for your question. The foam is open cell.

Thank you for your question. Home Depot does not cut the product. You should be able to cut the product with either a very sharp utility knife, an electric knife, or very sharp scissors. The 3 inch Memory Foam comes in one size of 24 inches wide by 72 inches in length. To meet the size you need, you would need to purchase two and cut them to meet the appropriate size. You can glue them together using 3M Spray Adhesive.

Thank you for your question. The 3 inch foam is 24 inches wide (2 feet) x 72 inches length (6 feet)

Thank you for your question. Prime Urethane is highly flammable when left uncovered and exposed to heat. We don't recommend any installation where this foam would be exposed to heat.

Thank you for your question. The product is not suitable to be a floatation device. The product is an open cell polyurethane foam and will absorb water. Product is recommended for cushion foam (pillows, bedding, etc)

Thank you for your question. We do not want anyone using the foam to be applied to walls. This is a reason we say it is not to be used as acoustical foam. We recommend our foam products to be used as cushion foams to make pillows, chair pads, etc.

Thank you for your question. Yes, we feel this product will be an excellent choice for this application.

Thank you for your question. The thickness is a personal choice. There are several reviews listed where customers feel the 3 inch foam is more than suitable for cushions and others prefer thicker cushion. Our foam products have an average density of 1.5 pounds/cubic foot.

Thank you for your question. We are not sure a waterproofing spray product would work. You can cover the foam with waterproof material to prevent it from getting wet.

Thank you for your question. The foam will oxidize (turn golded yellow) if left exposed. We recommend the product be covered with material.
