Verdict: if you want a mattress that feels genuinely soft and cushioned right where your shoulders and hips land, without the whole bed collapsing underneath you, the Destin Cove PT is worth a look. It is Sierra Sleep's pillow top hybrid, built 16 inches tall with a real coil system doing the support work underneath the softness, not just foam stacked on foam.
How it's built
- Four way stretch knit cover designed to move with you and stay cool against the skin
- Tri-layer plush quilt foam for the cushioned first touch of the pillow top
- Plush sculpted foam shaped to follow the body's curves
- High-density, quick-response memory foam for pressure relief at the shoulders and hips
- High-density firm foam transition layer between the comfort stack and the coils
- Wrapped coil support unit with Ashley Edge reinforcement around the perimeter
- High-density base foam foundation, 16 inches total, Twin through California King
The Destin Cove PT (Ashley model M332) leans further into softness than most hybrids by giving the comfort layers more room to work before the coils take over. The tri-layer quilt foam and sculpted foam create the initial plush sink, the memory foam layer follows through on pressure relief without holding onto body heat the way older foam does, and the wrapped coils keep that softness from turning into a slow bottom-out. Ashley Edge support reinforces the perimeter, so the mattress holds up when you sit on the side of the bed getting dressed, or sleep close to the edge, which matters more on a pillow top than most people expect going in.
Who it suits
- Side sleepers who want real cushioning at the shoulder and hip rather than a "plush" label on a firmer bed
- Back sleepers who like a soft surface but still want coil support underneath so the lower back doesn't sag through the night
- Couples who want the bounce and edge support of a coil system without losing motion isolation, since each wrapped coil compresses on its own
- Anyone replacing a worn-out pillow top who wants that same soft-on-top feel built over a longer-lasting hybrid core
It's probably not the right call for committed stomach sleepers or anyone who needs a firm, minimal-sink surface under their hips. Sierra Sleep builds firmer options in the same Destin Cove family for that.
What to know before delivery
The Destin Cove PT ships compressed in a box. Once it's unboxed and on its foundation, give it up to 48 hours to fully expand to its true shape and feel. It needs a compatible foundation or adjustable base, sold separately, and it's backed by a 10-year, non-prorated manufacturer warranty against defects in materials or workmanship.
A description can tell you what's in the mattress. It can't tell you how a plush pillow top feels under your particular shoulders and hips. Come lie on the Destin Cove PT at one of our Kentucky showrooms and find out before you buy.
What makes this mattress different
A pillow top with real depth
Tri-layer plush quilt foam and a plush sculpted foam layer stack up before you even reach the memory foam, giving the Destin Cove PT a noticeably deeper cushioned feel than a standard hybrid.
Four way stretch cooling cover
The knit cover stretches with your movement and is built to stay cool against the skin instead of trapping warmth over the softest part of the mattress.
Quick-response memory foam
High-density memory foam eases pressure at the shoulder and hip, then recovers quickly instead of holding you in a slow, heavy sink.
Ashley Edge perimeter support
Reinforcement around the edge of the coil unit keeps the sides of the mattress from caving in when you sit down to get dressed or sleep near the edge.
Wrapped coils for a quieter shared bed
Each coil in the support unit compresses on its own, so a partner rolling over or getting up early is far less likely to carry across to your side.
Ships in a box, ready in about 48 hours
The mattress compresses for delivery and needs roughly two days after unboxing on its foundation before it reaches full shape and feel.
10-year non-prorated warranty
Sierra Sleep backs the Destin Cove PT with a full 10-year non-prorated warranty against manufacturing defects.
Six sizes, one comfort level
Available in Twin, Twin XL, Full, Queen, King, and California King, all built to the same 16 inch pillow top construction.
A deeper comfort stack over a real coil core
The Destin Cove PT starts with a four way stretch knit cover, then gives you two dedicated comfort layers before the support system even begins: tri-layer plush quilt foam for the surface-level cushion of the pillow top, followed by plush sculpted foam shaped to follow the body. Next comes a high-density, quick-response memory foam layer, doing the pressure-relief work at the shoulder and hip without the slow, heavy sink older memory foam is known for.
Underneath that comfort stack sits a high-density firm foam transition layer, then a wrapped coil support unit reinforced with Ashley Edge along the perimeter, all resting on a high-density base foam foundation. The coils compress individually rather than as one connected surface, which is what keeps a bed this plush from bottoming out under regular use, and what keeps the edges stable when you sit or sleep near them. Sixteen inches total, the tallest build in the Destin Cove family. If a full pillow top turns out to be more give than you're after, the Destin Cove Plush shares the same coil and cover construction in a slightly lower 15 inch profile, and the Destin Cove Firm trades the pillow top for a firmer, flatter surface.

Side sleepers: the extra depth in the pillow top gives the shoulder and hip more room to sink in before the memory foam and coils take over, which is exactly what this sleeping position asks for.
Back sleepers who prefer softer support: you get the plush surface feel without losing the coil support that keeps the lower back from sagging through the night.
Couples sharing a bed: the wrapped coil unit compresses coil by coil, so a partner shifting position or getting up early is less likely to disturb your side, and the Ashley Edge perimeter keeps the mattress stable if either of you tends to sleep near the edge.
Anyone upgrading from a worn-out pillow top: this build is meant to replicate that familiar soft-on-top feel while adding a hybrid coil core underneath for support that lasts longer than an older all-foam bed.
Probably not for you if: you sleep on your stomach or need a firm, flat surface to keep your hips from sinking. The Destin Cove Firm is built for that; the Destin Cove Plush is a middle ground if you want less depth than a full pillow top.

Frequently asked questions
How firm is the Sierra Sleep Destin Cove PT?
It's a genuine plush pillow top, the softest and tallest mattress in the Destin Cove family at 16 inches. The tri-layer quilt foam and sculpted foam create real cushioning depth at the surface, and the memory foam layer beneath continues that softness at the shoulder and hip, before the wrapped coil unit takes over for support.
Is the Destin Cove PT a hybrid or an all-foam mattress?
Hybrid. A four way stretch knit cover and layered foam comfort system sit over a wrapped coil support unit with Ashley Edge perimeter reinforcement, so the plush top gets real coil support underneath instead of foam stacked on more foam.
Who sleeps best on the Destin Cove PT?
Side sleepers get the most out of the deep pillow top, since it gives the shoulder and hip extra room to settle in. Back sleepers who like a softer surface do well here too. Stomach sleepers and anyone needing a firm, flat feel should look at the Destin Cove Firm instead.
Will I feel my partner move around at night?
Less than you would on a traditional innerspring. The wrapped coils compress individually rather than as one connected unit, so movement on one side of the bed is far less likely to carry across to the other. The Ashley Edge reinforcement also keeps the perimeter steady if one of you sleeps near the edge.
Does the Destin Cove PT sleep hot?
It shouldn't. The four way stretch knit cover is built to stay cool against the skin, and the quick-response memory foam layer is designed to release heat rather than hold onto it the way older, denser memory foam does. A coil-based hybrid also breathes better than an all-foam mattress of the same height.
How long does the mattress take to reach full size after delivery?
Up to 48 hours. The Destin Cove PT ships compressed in a box, and once it's unboxed and placed on a supportive foundation, it needs roughly two days to fully expand to its true shape and feel.
Does Mattress Overstock offer an at-home trial on the Destin Cove PT?
No. Sierra Sleep mattresses, including the Destin Cove PT, do not include an at-home trial. The way to know if this pillow top is your feel is to lie down on it in your own sleeping position at one of our Kentucky showrooms before you buy it.
What's the warranty on the Destin Cove PT?
