Mattress Firm takes on Prime Day with its own epic sale — I've found the 5 best offers

1. Tempur-Pedic Tempur-Adapt Medium Hybrid Mattress (previous model): queen was $3,399 now $2,379 at Mattress Firm
This is the last-gen Tempur-Adapt, but it's not all too different from the current model that's available at Tempur-Pedic. As a hybrid, expect it to have better edge support and airflow than we experienced in our Tempur-Pedic Tempur-Adapt Mattress review. Only queen and king sizes are available, but buy from Mattress Firm and you'll be saving up to $330 versus purchasing the latest Tempur-Adapt model straight from Tempur-Pedic.

2. Zinus MyGel 10" Medium Memory Foam Mattress: twin was $459.99 now $183.20 with code PRIMETIME at Mattress Firm
Whether you need a mattress for your guest room or your dorm room, this budget all-foam model from Zinus is a near steal. (A queen is only $287.20 after all discounts.) Expect it to perform similarly to the Zinus Green Tea Memory Foam Mattress with a medium feel to suit side sleepers. You can upgrade to the 12" version if you need more height; it's also on sale with an additional 20% off after code PRIMETIME.

3. Beautyrest Silver BRS900 Extra Firm Mattress: twin was $1,199.99 now $391.99 with code PRIMETIME at Mattress Firm
Stomach sleepers, this deal is for you. This 11.75" hybrid features firm pocket coils along with a gel memory foam layer across the center of the mattress for lumbar relief. In addition to up to 59% off the MSRP, apply coupon code PRIMETIME for an extra 20% off. That brings the price of a queen-size Beautyrest Silver to $463.99 (was $1,399). That's less than most of our best firm mattress picks.

4. Tulo Bamboo 12" Green Tea Memory Foam Mattress: twin was $629.99 now $191.19 with code PRIMETIME at Mattress Firm
This memory foam mattress is wrapped in a breathable bamboo soft knit cover to help prevent overheating. With a medium-plush feel courtesy of the green tea-infused foam comfort layer, we think this is one for side sleepers to enjoy. It's a rather basic design otherwise, but the price is right if you're shopping for a college dorm, guest room, or your first apartment. A 62% discount from MSRP plus an extra 20% off with code PRIMETIME knocks the price of a queen-size to $263.99 (reg. $869.99).

5. Tulo 2" Gel Memory Foam Zoned Mattress Topper: twin was $59.99 now $31.99 with code PRIMETIME at Mattress Firm
If you don't need a whole new mattress, a bed topper provides an instant refresh for much less. As far as memory foam mattress toppers go, this one from Tulo is among the cheapest out there, but it provides targeted relief and support from head to toe, which is a hallmark of some of the best mattresses we've tested. A queen-size drops from $79.99 to $43.19 after coupon code PRIMETIME. If you need a more profound comfort boost, 3" and 4" toppers are also available on sale.
