Is a 2-inch topper thick enough?

For most sleepers it adds comfort but not transformation. It helps a mattress that is too firm; it will not rescue one that sags or has broken springs. Heavier sleepers should look at 3 inches or more.

Will my Full sheets still fit?

Usually yes. Two inches is a modest addition, and most Full fitted sheets have enough stretch. Deep-pocket sheets fit more comfortably.

Memory foam holds heat, and this topper has no gel or cooling layer. Hot sleepers may prefer a latex or gel-infused topper, or add a breathable mattress protector.

How long does it last?

Expect roughly one to three years of nightly use before it flattens noticeably. Rotating it regularly helps, and it lasts longer on a guest bed used occasionally.

Unroll it on the mattress and let it expand for about 24 to 48 hours. Air it in a ventilated room first if there is a foam smell.

Our take on the Sonoro Kate Memory Foam Mattress Topper, Full

The Sonoro Kate is a 2-inch memory foam mattress topper with a down-alternative fiber cover, sold in a Full size. It is a low-cost way to soften a firm or aging mattress without replacing it. Its thin profile means it adds cushioning more than it hides deep sagging or springs. Prices for this topper sit at the budget end of the memory foam topper market, so it is one of the cheaper ways to test whether foam suits your sleep.
