Mattress toppers are great at helping a hard mattress feel more comfortable. If you don’t want to invest in a new bed or your old mattress offers the right amount of support, a topper can give you a cloud-like feeling. You’ll want to look for a thick topper (3-4 inches) categorized as soft or medium-soft for the most dramatic effect. If you only need to bring your mattress to a medium-firm feel, try a topper on the thinner side (around 2 inches). There’s plenty of choice when it comes to toppers designed to soften your firm mattress. If you don’t need any extra support, a feather or synthetic topper could be a good option. These are exceptionally soft and plush, but lack some of the contouring and pressure relief seen in latex or foam toppers. If you need a combination of comfort and support, a latex topper would be a good pick.
