How can I save additional money on a cheap mattress?

Before you shop for a cheap mattress, it pays to learn about how a discount mattress is made. More expensive mattresses typically have damask ticking, thicker padding, higher coil counts, and a cushion sewn into the mattress. Coil count and configuration seem to have little effect on durability. Sagging in cheap mattresses is caused by the padding, not the coils. Therefore, when comparing mattresses look at for thicker, higher quality padding.
