Frequently Asked Questions About Mattress Firm
Does Mattress Firm have a sleep trial?
Yes, Mattress Firm advertises a 120-night sleep trial on many mattresses. Check the terms for your model before buying.
Which mattress brands does Mattress Firm sell?
It sells major brands including Serta, Sealy, Simmons Beautyrest and Purple, plus its own brands such as Sleepy's and tulo.
Does Mattress Firm offer financing?
Financing is offered to qualified customers, and offers can change through the year. Review the terms and any interest before you apply.
Can I get a Mattress Firm mattress delivered quickly?
Some mattresses are available for same day or next day delivery, depending on your zip code. Enter your zip on the site to see what applies.
Is it better to buy a Mattress Firm mattress online or in store?
Prices and offers can be similar, so it comes down to preference. Trying a mattress in store first and then ordering online is a popular route.
A mattress is a purchase you live with for years, so the sleep trial matters as much as the sticker price. Read the trial and return terms for the specific model you pick, since proprietary and third-party brands can have different warranty terms. Visiting a store to lie on a few models, then ordering online, is a common way to save time. Sale events often cluster around holiday weekends, so timing your purchase can lower the final price.
