Product Description

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).
