Comfortability: 

Once they do soften up, quilted mattresses are extremely comfortable and long-lasting.

Bounce: 

Quilted mattresses provide bounce a little bit.

Care: 

Quilting makes it harder to remove stains but if you protect your mattress with a mattress protector, this is not an issue.

Causing allergic and irritation:

The closed surface of the quilted mattress prevents dust mites from getting inside the mattress and causing irritation. When compared to a non-quilted mattress, the quilt is more breathable and also helps reduce heat levels.

Firm:

Quilted mattresses can add additional softness to the mattress. Therefore, such mattresses are much softer than non-quilted ones.

Temperature:

Quilted coverings are usually warmer since they have more material and are typically used on memory foam or polyurethane foam mattresses, which are already hotter.
