Every Prime Day, I’ll spot a mattress deal that reminds me how good this sale event can be. This year, a queen-sized SweetNight 14″ CoolNest Mattress, now just $379.51 at Amazon is the standout early Prime Day deal.
After extensively testing the SweetNight CoolNest for over a month, I found its cooling design rivals even the best mattresses we’ve tested. The 12″ model is always a budget favorite with a queen under $400 at SweetNight, but this weekend at Amazon the 14″ version has taken its place as the best affordable choice.
However, if I know one thing after three years of covering Amazon Prime mattress sales, it’s that these deals don’t stick around for long. Here’s why I think this $250 discount is the best early Prime Day deal I’ve seen so far, plus why I loved sleeping on the SweetNight CoolNest Mattress.
14″ CoolNest Memory Foam Mattress (queen): was $629.99 now $379.51
Over at SweetNight the 14″ model of the CoolNest Memory Foam Mattress is $469.99 for a queen. In this month’sAmazon mattress sales, however, a queen 14″ is down to $379.51, saving you over $250. While the CoolNest Memory Foam Mattress does come with perks such as a 100-night sleep trial when bought directly at SweetNight, a 10-year warranty still applies when you go via Amazon — and you do get free 90-day returns, although the mattress has to be in the box to claim your refund.

Why I’d buy the SweetNight CoolNest this weekend…
For my SweetNight CoolNest mattress review, I put the SweetNight CoolNest through vigorous lab-based and at-home testing. I found its contouring memory foam feel suited side sleeping the best, providing enough pressure relief to comfort the shoulders and hips.
Equipped with cooling tech like gel infusions, breathable cover, and heat-dissipating Phase Change Material, the SweetNight CoolNest kept me sleeping cool even through summer heatwaves.
Meanwhile, its price tag means it’s one of the most budget-friendly cooling models around; it even earned a spot in our best cooling mattressguide as the top choice for side sleepers on a budget.

Memory Foam Mattress (queen): $329
The Siena Signature Mattress may not be a dedicated cooling model like the SweetNight, but it boasts impressivetemperature regulation. Right now, a queen Siena Signature is $329, and it comes with good extras like a 10-year warranty and a 100-ight sleep trial. However, be aware that our Siena Signature Memory Foam Mattress review team found it only suitable for back and stomach sleepers, as it will be too firm for side sleeping. View Deal
