Signature Design by Ashley Full Size Firm Hybrid Mattress - 11 Inch with Lumbar Support Gel Memory Foam, Fiberglass Free, Mattress in a Box

Product Overview

This full-size mattress measures 52 inches wide by 74 inches long by 11 inches thick, compatible with most full bed frames. The hybrid design layers support foam, gel memory foam for pressure point relief, and power-packed wrapped coils that minimize motion transfer. The 4-way stretch knit cover provides a comfortable surface that reviewers describe as soft yet supportive. The mattress arrives vacuum-sealed in a box, requiring unboxing, cutting protective wrap, and unrolling to expand. While safe to sleep on immediately, it may take 72+ hours for any residual scent to dissipate and for complete expansion. Delivery options include inside-front-door delivery, room placement, setup with old mattress removal for additional fees. The mattress is marketed as suitable for adults and kids, with a firm feel that many reviewers characterize as extra firm. The construction is fiberglass-free, addressing common concerns about material safety. The top features white fabric with lavender accents, while sides have dark fabric with purple thread patterns and faux button tufting.

Design & Build

The Signature Design by Ashley mattress features an 11-inch profile constructed with multiple layers. The base consists of support foam that provides foundational stability. Above this, gel-infused memory foam targets pressure points and adds lumbar support. The core incorporates wrapped coils that are individually encased to reduce motion transfer and enhance durability. The top layer is a 4-way stretch knit cover that reviewers describe as soft and comfortable, with white fabric and lavender accents adding visual appeal. Sides are finished with dark fabric featuring purple thread patterns and faux button tufting for a traditional mattress look. The entire construction is fiberglass-free, addressing safety concerns common in budget mattresses. The mattress arrives tightly rolled and vacuum-sealed in plastic wrap within a cardboard box, requiring careful unboxing to avoid damage. Setup involves cutting the plastic, unrolling the mattress, and allowing it to expand, which typically happens within minutes to hours. The design emphasizes firm support with minimal plushness on top, making it suitable for sleepers who prefer a solid feel. Cleaning is straightforward with the removable cover, though specific care instructions should be checked. The mattress is heavy at 51.6 pounds, requiring assistance for movement, especially upstairs.

Build quality receives positive remarks from reviewers, who note intact delivery despite sometimes battered boxes. The materials feel substantial, with no reports of immediate defects or odors beyond temporary packaging scent. The hybrid construction combines the bounce of coils with the contouring of foam, avoiding the extreme sink of all-foam models. The wrapped coils are praised for minimizing partner disturbance, a key benefit for couples. The gel memory foam layer is thin enough to maintain firmness while providing pressure relief. The 4-way stretch cover adds a plush touch without compromising support, though it is not described as cooling. The mattress edges hold up well when sitting, with reinforced sides preventing excessive sag. Aesthetics are considered attractive, with the white and lavender design blending into various bedroom decors. The faux button tufting on sides adds a classic detail. Durability appears promising based on initial reviews, though long-term performance requires more time. The bed-in-a-box packaging ensures the mattress arrives undamaged if handled properly, with expansion typically reaching full height quickly. Maintenance involves rotating periodically for even wear, though specific guidelines are not provided. Overall, the design prioritizes functional support with thoughtful material choices for a mid-range price point.

Performance

Reviewers consistently report that this mattress provides firm support that alleviates back pain and improves sleep quality. Many describe it as extra firm, with minimal compression when sitting or lying down. The hybrid construction offers a balance between support and comfort, with the gel memory foam layer cradling pressure points without excessive sink. Motion isolation is effective, with wrapped coils reducing disturbance from partner movement. Sleepers note reduced morning stiffness and numbness, particularly in arms and hands, attributing this to the firm surface that promotes spinal alignment. The mattress does not retain heat excessively, with the gel infusion helping maintain a neutral temperature. However, some mention it feels firmer than expected, which may require adjustment or a mattress topper for those preferring plushness. The firmness remains consistent over initial weeks, with slight softening possible over time. Edge support is adequate for sitting, though not emphasized in reviews. The mattress works well on various bases, including platform beds and box springs, without sagging. Overall performance meets expectations for a firm hybrid at this price, with particular strength in pain relief and motion isolation.

Real-world use highlights the mattress's suitability for back and side sleepers who need support. Reviewers with back pain, including sciatica, report significant improvement after switching to this mattress. The firm surface prevents sinking that can misalign the spine, though stomach sleepers may find it too firm. The hybrid design provides enough bounce for ease of movement and intimacy, unlike all-foam options that can feel restrictive. Temperature regulation is satisfactory, with no complaints about overheating, though it is not marketed as actively cooling. The mattress expands fully within hours, with residual scent dissipating quickly, allowing immediate use. Durability appears robust in short-term assessments, with no signs of premature sagging or coil noise. However, long-term resilience is untested in available reviews. The firmness may be too intense for lightweight sleepers or those used to plush surfaces, but adding a topper customizes comfort. Performance in motion isolation earns praise from couples, who experience less disturbance. The mattress maintains its shape well, with no noticeable dips after weeks of use. Trade-offs include the weight, making repositioning difficult, and the firm feel that might not suit all preferences. Reviewers emphasize it delivers on its promise of firm support with quality materials, offering value for money.
