Amazon Prime Day deals are underway, but not all of the best savings are found on Amazon. I'm actually finding that competing mattress sales elsewhere that beat Prime Day deals, including top-performing picks from our tests in the Good Housekeeping Institute Textiles Lab.
As a shopping editor, I regularly vet deals and track prices to find the best discounts on the best items at the right time. Although a holiday weekend typically sees the steepest mattress deals, if you're in the market for a new mattress, you'll want to shop off Amazon for our experts' favorite mattresses.
Mattress Firm's Competing Sale
THE DEAL: Until July 15, Mattress Firm is offering up to $700 off select mattresses from some of our experts' favorite brands like Sleepy's, Sealy, Serta and Beautyrest.
WHY WE LOVE IT: Serta's Perfect Sleeper Collection is a favorite among our experts. The Charlotte 2.0 has breathable coils and three different comfort zones to ensure a great night's sleep. We especially love the Perfect Sleeper Hybrid Mattress, which is on sale for over 25% off.

Helix's Competing Sale
THE DEAL: Going on now through July 31, take 27% off with our exclusive code GH27. This is slightly better than Helix's general Dream Day sale at 25% off sitewide and ends July 11.
WHY WE LOVE IT: The Helix Dusk Luxe is one of our Lab pros' favorite mattresses for couples or individuals who sleep on their back and stomach. They like that the mattress has a responsive feel with a bit more bounce than your average hybrid.

Bear Mattress's Competing Day Sale
THE DEAL: The brand is currently offering a 35% discount sitewide, but you can take 40% off sitewide with our exclusive code GH40 until July 14.
WHY WE LOVE IT: "I suffer from back pain and with this mattress, I wake up pain-free," said one GH tester for the Bear Elite Hybrid. Our pros in the Textiles Lab were also impressed by this model's pressure-relieving zones specifically designed for spinal alignment and back-pain relief.

Nolah's Competing Sale
THE DEAL: Right now, take 35% off sitewide from Nolah, plus save an additional $50 on your purchase with our exclusive code GH50 until July 14.
WHY WE LOVE IT: The Nolah Original features superb pressure-relieving memory foam that won't make you overheat this summer — our testers and panelists gave it top scores for maintaining a comfortable, cool temperature. Nolah's deals have been more impressive as of late, but our exclusive $50 discount takes it one step further than the brand's identical Memorial Day sale.
