Signature Design by Ashley King Size Augusta2 Mattress - 12 Inch Euro Pillow Top Hybrid with Lumbar Support Gel Memory Foam, Fiberglass Free, Mattress in a Box

Product Overview

This king-size mattress measures 79.5 inches long by 76 inches wide with a 12-inch thickness profile. The construction begins with a 1-inch high-density foam encasement around the perimeter for edge support. Inside, pocketed coils provide the core support system, surrounded by multiple foam layers: 1.5 inches of firm convoluted quilt foam, 2 inches of firm support foam, 0.5 inches of gel memory foam specifically positioned for lumbar support, and 0.75 inches of high-density base support foam. The cover consists of 53% viscose, 20% polyester, 11% filament poly, and 11% barrier coating, treated with luxury nano stain protection. A concealed micro-teeth zipper with patented zip tie closure allows for cover removal, though care instructions specify spot cleaning only. The mattress weighs 113.1 pounds and ships compressed in a single box with no assembly required. It's compatible with adjustable bases and comes with a 10-year non-prorated warranty. Reviewers note the mattress arrives tightly rolled and expands quickly, though some report initial off-gassing odors that dissipate within days. The firm comfort level works best for those preferring substantial support, though some sleepers find it too firm initially before it breaks in over several weeks.

Design & Build

The Augusta2 mattress employs a structured hybrid design with clearly defined layers. Starting from the bottom, 0.75 inches of high-density base support foam provides foundational stability. Above this sits the pocketed coil system, which offers individualized support while minimizing motion transfer between sleeping partners. The coils are surrounded by a 1-inch high-density foam encasement that reinforces the mattress edges, preventing roll-off and extending the usable sleep surface. Moving upward, 2 inches of firm support foam creates a transitional layer between the coils and comfort materials. The key feature is the 0.5-inch gel memory foam layer specifically positioned for lumbar support, designed to contour to the lower back's natural curve. Topping the construction is 1.5 inches of firm convoluted quilt foam, creating a Euro pillow top that provides surface cushioning without compromising the mattress's overall firmness rating. This layered approach aims to deliver both support and pressure relief in targeted areas.

The mattress cover uses a blend of 53% viscose, 20% polyester, 11% filament poly, and 11% barrier coating. This combination creates a breathable surface with stain-resistant properties thanks to luxury nano treatment. A concealed micro-teeth zipper runs around the perimeter, allowing for cover removal when needed, though care is limited to spot cleaning. The zipper features a patented zip tie closure system that secures the bed bug encasement, creating a protective barrier. At 12 inches thick, the mattress presents a substantial profile that fits standard deep-pocket sheets. The compressed shipping method allows the 113.1-pound king mattress to arrive in a manageable box, though reviewers note that re-compression for returns proves challenging without specialized equipment. The overall construction emphasizes durability with a 10-year warranty backing the materials and workmanship.

Performance

Reviewers report the Augusta2 provides firm support that benefits back sleepers and some side sleepers. Many note improved spinal alignment and reduced morning back pain compared to their previous mattresses. The hybrid design offers a balance between the responsiveness of coils and the contouring of foam, with several sleepers mentioning they experience less motion transfer than with all-foam mattresses. The targeted lumbar support receives particular praise from back sleepers who appreciate the extra reinforcement in that area. However, firmness perceptions vary significantly—some find it perfectly supportive while others describe it as too firm initially. Multiple reviewers mention the mattress softens slightly during the first few weeks of use, transitioning from very firm to medium-firm as the materials break in. This break-in period means initial impressions may not reflect long-term comfort, with several users reporting increased satisfaction after the first month.

Temperature regulation appears adequate for most sleepers, with the gel memory foam layer intended to address heat retention in the lumbar area. Some reviewers report minimal heat buildup, while others don't mention temperature as a concern. The pocketed coil system provides good airflow through the mattress core. Edge support proves substantial thanks to the foam encasement, allowing sleepers to utilize the full surface area. Durability concerns emerge in some reviews, with one user reporting a large dent developing after a month of use in an area with less frequent pressure. Off-gassing odors are noted by several buyers initially, but most report the smell dissipates within a few days when the room is well-ventilated. The mattress maintains its shape well after expansion, though returning it presents logistical challenges due to the difficulty of re-compressing the materials without specialized equipment.
