Mattress topper sales FAQs
Are mattress toppers worth it?
So, do mattress toppers work or are they just a waste of money? Well, if you're toally fine with your current mattress don't find it to be too soft, too hard, or too warm, then buying a mattress topper isn't necessary.
However, if you feel that your bed isn't offering you the support and comfort you need but don't have the budget for a new mattress, a mattress topper could be all you need to help you get better sleep. If your mattress is too firm, a memory foam mattress topper is great for adding some softness, while you can also get firmer toppers to add support to a mattress that's too soft.
Meanwhile, if you feel that your mattress is trapping body heat or you experience overheating and night sweats, then there are plenty of cooling mattress toppers designed to add temperature control to your mattress.
Also, If you like the feel of memory foam but have a spring mattress, you can add a memory foam topper to simulate the feel of the best hybrid mattresses or the best memory foam mattresses. A thick (3" to 4") mattress topper is also great to extend the life of your mattress, especially if your mattress is reaching the 10-year mark but you're not ready to buy a new one.
How do I choose a mattress topper?
We've created a handy comprehensive guide on how to choose a mattress topper, but here's a quick summary:
- Consider the type. Most mattress toppers come in one of four materials: memory foam, latex, down, or hybrid. Memory foam is most popular as it softens hard beds and tends to be the cheaper option, but natural latex foam offers a breathable, hypoallergenic surface. Skip down mattress toppers altogether as they are incredibly thin and don't leave an impact, but you can go for a hybrid mattress topper with a down pillow top and a supportive foam base.
- Consider what you need. Does your bed need softening? Choose a plush memory foam mattress topper. Could it be firmer? Look for a mattress topper with a form option. Experience night sweats? Look for a mattress topper with cooling tech such as a heat-dissipating cover or ventilated foam. Do you weigh over 230lbs? Look for something on the firmer side.
- Consider your sleep position: Side sleepers will need more cushioning, while stomach sleepers will need firmer support. Back sleepers should go for something with balanced support and comfort.
- Consider the height. Never choose a mattress topper below 2" tall or above 4" high. A thin mattress topper won't make a difference and an ultra-thick mattress topper will make your bed too tall and squidgy. 3" toppers will suit most beds, but 2" mattress topper are good for new beds and 4" mattress toppers are great for older beds or side sleepers who need extra plushness.
When is the best time to buy a mattress topper?
Like mattress sales, mattress topper sales tend to offer the biggest discounts during major sales periods like Presidents' Day, Memorial Day, and Black Friday. The current Amazon Prime Day sales are also a great time to look for mattress topper bargains.
Now the summer Prime Day deals have drawn to a close, the next big sales events will be the Labor Day mattress sales, which starts around mid-August and peaks around Labor Day (September 1), and we'll be updating this list regularly with the best early deals that emerge next month. To get the best deal, shop for a mattress topper in the weeks surrounding this major date.
