Sierra Sleep Hybrid 1300 Mattress

The verdict: if you want plush, body-hugging comfort with the support and edge stability of coils underneath, the Sierra Sleep Hybrid 1300 earns a real look. It is built for sleepers who liked the sink-in feel of a foam mattress but got tired of the edge collapsing or the whole bed sleeping warm.
How It's Built
The Hybrid 1300, part of Ashley's M436 series, starts with a 4-way stretch cover finished in pillow pocket quilting, so the surface itself has a soft give before you ever reach the foam underneath. Below the cover sits a layer of high-density response memory foam over a high-density whisper foam layer, the pairing responsible for the plush comfort rating Ashley assigns this model. Under the foam is the coil system: 720 individually wrapped, power-packed 15-gauge coils that flex on their own instead of shifting as one connected unit. Two perimeter rows of heavier 13-gauge wrapped coils, reinforced with Ashley's steel edge encasing, run the full border of the mattress, so the sides hold their shape when you sit down to tie your shoes or sleep near the edge instead of caving in underneath you. Stacked together, the build measures 13 inches, with a queen mattress weighing in around 91 pounds.
Feel and Support
Plush is the operative word here. The foam layers let you settle in at the shoulders and hips rather than resting on top of a firm surface, while the wrapped coils underneath keep that softness from turning into a dip in the middle of the bed. Because each coil compresses independently, a partner turning over or getting up in the night is far less likely to wake you, a real step up from older innerspring designs where one coil moving tugs on the coils around it. The mattress is also compatible with adjustable bases, so it works whether you sleep flat or prefer the head or feet raised.
Who It Suits
- Side sleepers who want pressure relief at the shoulder and hip without losing support underneath
- Anyone upgrading from an all-foam mattress who missed having a real edge to sit on
- Couples who want motion isolation without going back to a firm, coil-only feel
- Sleepers who simply prefer a softer, contoured surface over a firm one
If you run hot on plush memory foam, or you specifically want a firm mattress that holds you up rather than lets you settle in, this is not the model to force. Ashley builds firmer options within the Sierra Sleep line for that preference, and our floor team can point you toward them.
Setup and Fit
Like most mattresses in this class, the Hybrid 1300 ships compressed in a box and needs about 48 hours to fully expand once it is unboxed in the room. It carries a 10-year non-prorated warranty and comes in Full, Queen, King, and California King.
Specs only tell you so much about plush comfort. The way a coil bed compresses under your actual hips and shoulders is something you feel, not read. Come lie on the Hybrid 1300 at one of our Kentucky showrooms before you decide.
What makes this mattress different
720 individually wrapped coils
Power-packed 15-gauge wrapped coils flex on their own under your body, so support follows your shape instead of one firm slab underneath the foam.
Steel-reinforced edge support
Two perimeter rows of heavier 13-gauge wrapped coils, backed by Ashley's steel edge encasing, keep the border from collapsing when you sit down or sleep near the side.
Plush, pressure-relieving comfort
A high-density response memory foam layer over a high-density whisper foam layer gives shoulders and hips somewhere to sink in, the pairing behind this model's plush rating.
Pillow pocket quilted cover
A 4-way stretch cover finished with pillow pocket technology adds a soft, quilted layer right at the surface before you reach the foam and coils below.
Motion isolation from wrapped coils
Because each coil compresses independently, a restless partner or an early riser is far less likely to disturb the rest of the bed.
Adjustable base compatible
Works flat on a standard foundation or on a base that raises the head or feet, so it fits more than one bedroom setup.
13 inches of hybrid construction
Foam, coils, and cover stack to a genuine 13 inches, with a queen mattress weighing in around 91 pounds.
10-year non-prorated warranty
Backed by Ashley's 10-year non-prorated warranty for long-term peace of mind on the build.
A plush hybrid that leans on coils, not just foam, for support
The Hybrid 1300 opens with a 4-way stretch cover finished in pillow pocket quilting, adding a soft, tufted feel at the very top before you reach anything underneath. Below that sits a high-density response memory foam layer over a high-density whisper foam layer, the combination that gives this mattress its plush comfort rating and lets shoulders and hips settle in rather than rest on a hard surface.
Underneath the foam is where this model earns the word hybrid: 720 individually wrapped, power-packed 15-gauge coils that each flex on their own instead of moving as a connected unit, plus two perimeter rows of heavier 13-gauge wrapped coils reinforced with Ashley's steel edge encasing running the full border. That perimeter reinforcement is what keeps the edge from caving in when you sit down to get dressed or sleep close to the side. All of it stacks to 13 inches total, and the mattress ships compressed in a box, expanding fully within about 48 hours of being unboxed in the room.
If plush with coils under it sounds right but you want to compare feel and firmness in person, our Kentucky showroom floors carry the Hybrid 1300 alongside other Sierra Sleep builds so you can lie on more than one before deciding.

Side sleepers: the plush foam layers give shoulders and hips somewhere to settle in, easing the pressure points that a firmer surface tends to aggravate.
Couples: individually wrapped coils compress on their own, so a partner shifting or getting up early is far less likely to carry across the bed and wake you.
Anyone who sits on the edge of the bed often: the reinforced perimeter coils and steel edge encasing keep the border stable for tying shoes, sitting to talk, or getting in and out through the night.
Sleepers coming from an all-foam mattress: this build keeps the sink-in comfort but adds a coil layer underneath for support and a defined edge that all-foam beds usually lack.
People who run warm on thick memory foam: the wrapped coil layer promotes airflow underneath the foam that a solid foam core does not allow.
Probably not for you if: you specifically want a firm, on-top-of-the-bed feel. This is a plush mattress by design, and a firmer Sierra Sleep model on our floor will suit that preference better.

Frequently asked questions
How firm is the Sierra Sleep Hybrid 1300?
It is built as a plush mattress. The high-density response memory foam and high-density whisper foam layers let you settle in at the shoulders and hips, while the wrapped coil system underneath keeps that softness supported rather than letting you bottom out.
Does the Hybrid 1300 come with an at-home trial?
No. Sierra Sleep by Ashley beds, including the Hybrid 1300, do not include an at-home trial. The way to know if the feel is right for you is to lie on it in person, which is exactly what our Kentucky showrooms are set up for: try it before you buy.
Is this a memory foam mattress or a hybrid?
It is a genuine hybrid. Foam layers sit on top for the plush feel, while 720 individually wrapped, power-packed 15-gauge coils underneath provide support, along with reinforced 13-gauge perimeter coils for the edge.
Will the edges of this mattress hold up over time?
Edge support is one of the stronger points of this build. Two perimeter rows of heavier-gauge wrapped coils, backed by Ashley's steel edge encasing, are built specifically to resist the sagging that softer, unreinforced edges develop.
Can I use the Hybrid 1300 on an adjustable base?
Yes. The mattress is compatible with adjustable bases as well as standard flat foundations, so it works whether you like the bed flat or prefer raising your head or feet.
How long does it take to expand after unboxing?
The Hybrid 1300 ships compressed in a box. Once it is unboxed and laid flat in the room, plan on roughly 48 hours for it to fully expand to its true 13-inch height.
What sizes is this mattress available in?
Full, Queen, King, and California King.
What warranty comes with this mattress?
The Hybrid 1300 is backed by a 10-year non-prorated warranty.
Can I see this mattress in person near me?
Yes, and with a plush hybrid that is genuinely the better way to decide. Mattress Overstock is a Kentucky-owned company with showrooms in Lexington, Georgetown, Somerset, London, and Richmond. Come lie on the Hybrid 1300 in your own sleeping position before you commit, and because everyone on the floor is paid the same no matter which brand you choose, the guidance you get stays honest.
