The ultra-slim yet supportive firm 6-inch Mattress by Ashley turns any bunk, trundle, or guest bed into a budget-friendly sleep upgrade. 

Its 6-inch low-profile firm mattress design saves vertical space without sacrificing comfort. 

The feel stays solid and stable. This suits back and stomach sleepers who need consistent spinal alignment. 

Moreover, a layer of super soft foam cushions pressure points so shoulders and hips rest easily. 

Beneath, a high-density base foam core delivers dependable support night after night. 

And, a breathable stretch-knit cover moves with the sleeper and encourages airflow for a fresher surface. 

The mattress arrives compact, unrolls quickly, and works with most adjustable bases. 

Lastly, shoppers enjoy free nationwide delivery and a limited warranty (stated on the product card) from Cloudy Mattress (an authorized Ashley partner).

WE'VE GOT ANSWERS

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

The 6-inch profile fits typical bunk and loft clearance, and its firm feel prevents bottoming out. The manufacturer does not expressly label it “bunk bed compatible,” so measure your frame first.

No. The mattress can rest on any solid platform, slats spaced under 3 inches apart, or an adjustable base.

The manufacturer does not publish a specific weight rating for this model. However, most 6-inch foam mattresses can comfortably support up to about 250 lb per sleeper. For higher loads, consider a thicker profile.

Yes. The firm core offers full-body support for adults, especially back and stomach sleepers. Heavier side sleepers may prefer a thicker option for deeper pressure relief.

The bed typically reaches usable firmness within a few hours of unboxing. Allow up to 48 hours for the foam to achieve its full height and feel before assessing comfort.
