The 8 Best Mattress Toppers For Sleep Number Beds

If you’re looking to bring an extra layer of comfort or support to your Sleep Number bed, a mattress topper can be the perfect solution. The best mattress toppers for Sleep Number beds are made from a variety of materials including supportive memory foam and cooling bamboo and are designed for side, stomach, and back sleepers.

Can You Put A Mattress Topper On A Sleep Number Bed?

According to the Sleep Number Sleep Professional I spoke to on the phone, you can put any kind of mattress topper on a Sleep Number bed. Depending on your preferences, a topper can make your mattress firmer, softer, cooler, or warmer. In general, side sleepers may prefer soft toppers to alleviate pressure points on the shoulders and hips. Back sleepers might prefer medium-firmness toppers that support the spine. Stomach sleepers may want firm toppers that give their spine the support it needs without feeling like their face is sinking into the mattress.

Which Material Should You Choose For Your Mattress Topper?

• Memory foam toppers mold to the shape of your body so that weight is distributed evenly, pressure points are relieved and movement is absorbed. However, memory foam can retain body heat, which might be uncomfortable for hot sleepers. If you’re looking for something cooler, a textured memory foam topper or one infused with cooling gel might be a good choice.
• Latex mattress toppers are typically firmer than memory foam, with a little more bounce and less exact body contouring, but they still offer the same relief for painful joints. Natural latex toppers are a breathable option.
• Down mattress toppers are fluffy, durable, and temperature-regulating. They need to be shaken out occasionally to re-fluff and can stir up allergies in some people.
• Down-alternative toppers are more affordable than down but have a similar soft feel and are typically hypoallergenic. Over time they can get lumpy and may not last as long as down.
• Bamboo mattress toppers offer a breathable and cooling night’s rest for hot sleepers, plus they’re moisture-wicking, hypoallergenic, and silky-soft.

With that in mind, take a look at some of the best mattress toppers for Sleep Number beds that will make your rest even more comfortable.

Helpful Amazon review: “I was skeptical about this mattress pad. I was afraid that the lavender would be overpowering and get old quickly but decided to try it anyway. I am really pleased. [...] Honestly, I have not slept that well in ages. I have a Sleep Number bed and it is set at 65. I like a firm mattress but a soft top. [...] I love the combination. The lavender scent is only noticeable when you pull back the covers to get in bed, very light scent.”

If you’re using this topper for the first time, the brand recommends tumble drying on low to fluff the fibers.

My comfortable bed is more so now and my fitted sheets are easier to place over the mattress corners due to elastic straps designed to hold topper in place. I've washed and dried this item before use following the instructions provided and the process went without issue. This topper was an excellent value and I recommend it.”
