I've tested America's firmest mattresses — this is the one I'd buy in the Labor Day sales

For stomach sleepers, waking up without back pain is a rarity. I used to endure a painful morning routine, until discovering the Plank Firm mattress. Currently on a 30% off Labor Day sale, this mattress promises fresh mornings.

The Plank Firm stands out with its double-sided construction, rivaling the top-tier mattresses in terms of quality. Its ultra-firm, flat profile is a dream for stomach sleepers and many back sleepers, ensuring full-body support. This alignment is crucial for stomach sleepers, preventing back strain that softer mattresses can cause.

For stomach sleepers it's a win-win. The Plank Firm provides exceptional support, holding the spine straight and allowing the body to relax. Yet, it may not be everyone's cup of tea. For those seeking a bit of softness, the Labor Day sales offer a variety of options.

While the Plank Firm is the top pick for stomach sleepers, the mattress market is full of other firm contenders. The Plank Firm Luxe, a 30% off sale, is a hybrid mattress with springs for better airflow but slightly less edge support. Meanwhile, the Siena Signature, a budget-friendly memory foam mattress, offers firm comfort and is a good value at $349.
