Sierra Sleep Destin Cove Plush Mattress
Couldn't load pickup availability
The Sierra Sleep by Ashley Destin Cove Plush is built for sleepers who want a soft, cushioned top layer without giving up the steadier support a coil system provides underneath. This 15 inch hybrid (Ashley model M331) leans plush at the surface and stays supportive at the core, a combination side sleepers and pressure sensitive backs tend to ask for on our showroom floor.
How it's built
- A four way stretch knit cover on top, chosen for a smooth, breathable surface that stays cool to the touch
- Tri-layer plush quilt foam directly beneath the cover, the layer doing most of the cushioning work
- High-density quick-response memory foam underneath that, for pressure relief without a slow, heavy sink
- An additional high-density comfort foam layer that helps spread your weight before you reach the coils
- A wrapped coil support core with Ashley Edge reinforcement around the perimeter, built to hold the edge and limit motion transfer across the bed
- A high-density foam foundation underneath the coils for a stable base
Layered together, the build reads plush on first touch and firmer as your weight settles in, which is how a well built hybrid should feel. The quilt foam and memory foam absorb the initial pressure at your shoulders and hips, then the wrapped coils take over and keep the mattress from bottoming out. The Ashley Edge reinforcement also means you can sit or sleep near the edge of the bed without feeling like it is about to give way, useful in a queen or full where two people share the space.
Motion transfer is the other place the coil design earns its keep. A wrapped coil system compresses coil by coil instead of as one connected unit, so a partner turning over or getting up early is far less likely to travel across the bed and wake you.
Who it suits
Side sleepers who want cushioning at the shoulder and hip without sinking too deep will likely be the best fit here. Back sleepers who prefer a plusher surface with some give, rather than a flat, firm feel, also tend to land on this mattress. If you run warm at night, the knit cover and quick-response foam are built to move heat off the surface rather than trap it against you the way older, denser memory foams can.
If you sleep almost exclusively on your stomach, or you know you need a firm, minimal give surface to keep your spine level, this plush build is probably softer than what you are looking for. The Destin Cove line also comes in a Firm and a Pillow Top version if the plush feel ends up being more give than you want once you lie down on it.
The mattress ships compressed in a box. Give it up to about 48 hours after unboxing to fully expand before judging the feel, and set it on a supportive foundation, platform bed, or adjustable base rather than an old, worn out box spring. Sierra Sleep backs the Destin Cove Plush with a 10-year non-prorated warranty, and it is made in the USA.
Available in Twin, Twin XL, Full, Queen, King, and California King. The best way to know if a plush hybrid is your feel is to lie down on one for a few minutes in your own sleep position. Come try the Destin Cove Plush at one of our Kentucky showrooms before you decide.
What makes this mattress different
Plush comfort over real coil support
A tri-layer quilt foam and memory foam top give you a soft, cushioned surface, while a wrapped coil core underneath keeps the mattress from sinking too far.
Four way stretch cooling cover
A smooth, breathable knit cover stretches with you and stays cool to the touch instead of trapping heat against the surface.
Quick-response memory foam
High-density quick-response memory foam cradles pressure points at the shoulder and hip without the slow, heavy sink of older memory foam.
Ashley Edge perimeter reinforcement
Reinforcement around the edge of the coil core means you can sit or sleep near the side of the bed without feeling like it will give way.
Wrapped coils quiet a shared bed
Each coil compresses on its own, so a partner turning over or getting up early is far less likely to travel across the mattress and wake you.
Ships in a box, ready in about 48 hours
The mattress compresses for delivery and needs roughly two days after unboxing to fully expand before it is ready for regular use.
10-year non-prorated warranty
Sierra Sleep backs the Destin Cove Plush with a full 10-year non-prorated warranty, and it is made in the USA.
Six sizes, one comfort level
Available in Twin, Twin XL, Full, Queen, King, and California King, all built to the same plush feel and construction.
Plush on top, coil-supported underneath
The Destin Cove Plush stacks a four way stretch knit cover over tri-layer plush quilt foam, then a layer of high-density quick-response memory foam, then an additional high-density comfort foam layer. Together those layers do the cushioning work at the surface, cradling the shoulder and hip without the slow sink of older memory foam.
Underneath sits a wrapped coil support core with Ashley Edge reinforcement around the perimeter, all resting on a high-density foam foundation. The coils compress individually rather than as one connected unit, which keeps the mattress from bottoming out, limits how much motion carries across to a partner's side, and holds the edge steady when you sit or sleep near it. The result is a mattress that feels plush where you land and stays supportive as your weight settles in, at 15 inches total. If plush turns out to be more give than you want, the Destin Cove Firm and Destin Cove Pillow Top share the same coil and cover construction with a different comfort layer on top.

Side sleepers: the plush quilt foam and memory foam cushion the shoulder and hip, the two pressure points side sleeping loads first.
Back sleepers who want some give: this build suits back sleepers who find a flat, firm surface uncomfortable and want cushioning without losing support underneath.
Couples and shared beds: the wrapped coil core plus Ashley Edge reinforcement means a partner's movement is less likely to carry to your side of the bed, and the perimeter holds up when someone sits or sleeps near the edge.
Hot sleepers who like a plush feel: the four way stretch knit cover and quick-response memory foam are built to keep heat from building the way older, denser memory foam can, so you get a soft feel without the trapped warmth.
Probably not for you if: you sleep on your stomach or need a firm, minimal give surface to keep your spine level. The Destin Cove Firm and Destin Cove Pillow Top share the same build with a different comfort layer if plush turns out to be more give than you want.

Frequently asked questions
What does "plush" mean on the Destin Cove Plush?
Plush is the softest of the three comfort levels Ashley builds into the Destin Cove line. The tri-layer quilt foam and memory foam on top give you noticeably more cushioning at the surface than the Destin Cove Firm or Pillow Top, while the wrapped coil core underneath keeps the mattress from feeling like it sinks too far.
Is the Destin Cove Plush a hybrid or an all-foam mattress?
It is a hybrid. A four way stretch knit cover and layered foams sit on top of a wrapped coil support core with Ashley Edge perimeter reinforcement, so you get the plush comfort of foam with the airflow and edge support of coils underneath.
Who sleeps best on the Destin Cove Plush?
Side sleepers and back sleepers who prefer a softer surface tend to do best here. The plush quilt foam and memory foam cushion the shoulder and hip, while the coil core keeps the mattress from bottoming out under you. Stomach sleepers and anyone who needs a firm, flat surface will likely find it too soft.
Does the Destin Cove Plush sleep hot?
It should not. The four way stretch knit cover is built for airflow, and the quick-response memory foam layer is designed to move heat off the surface rather than trap it the way older, denser memory foam can. Paired with a coil core underneath, air moves through the mattress more freely than in an all-foam bed.
How much motion transfer will I feel from a partner?
Less than you would on a basic innerspring. The wrapped coils compress individually instead of as one connected unit, so movement on one side of the bed is less likely to travel across to the other. The Ashley Edge reinforcement also keeps the perimeter stable if one of you sits or sleeps near the edge.
Can I put the Destin Cove Plush on an adjustable base?
It sits well on a supportive foundation, platform bed, or adjustable base. Give it up to about 48 hours after unboxing to fully expand before you judge the feel, and avoid setting it on an old or sagging box spring, which will undercut the support the coil core is built to provide.
Is there an at-home trial with the Destin Cove Plush?
No. Sierra Sleep beds, including the Destin Cove Plush, do not come with an at-home trial. The way to know if this plush hybrid is your feel is to lie down on it before you buy, in your own sleep position, at one of our Kentucky showrooms.
