DLX mattress review: the reason to consider it
DLX is worth comparing if you want more control over firmness than a single fixed-feel mattress provides. The Premier Hybrid’s adjustable comfort layer is the central feature to investigate. It gives you a different buying proposition from choosing a sealed mattress and hoping the first firmness works.
That flexibility comes with practical questions: which layer can be changed, what help is included, and how would you handle a refund if the mattress still does not suit you? Get those answers before ordering.
Premier Hybrid: current options
The current Premier Hybrid listing offers 12- and 14-inch profiles, soft through firm choices including medium-firm, and selected split-firmness combinations. Confirm availability for your size; do not assume every combination is offered in every size.
| Construction detail | Manufacturer specification |
|---|---|
| Adjustable comfort layer | 3-inch Premier Performance foam, listed at 2.4 lb density |
| Coil support | 6- or 8-inch pocketed-coil system, depending on profile |
| Surface cushioning | Quilted fabric, fiber and LoftAdapt foam |
| Firmness selection | Soft, medium, medium-firm, firm and selected internal split options |
These are specifications, rather than measured Yawnder pressure-relief, cooling or durability results. A denser foam specification is useful for comparison but does not establish a guaranteed lifespan.
DLX also groups products into hybrid and double-sided collections. Choose a model-specific specification sheet rather than applying Premier’s comfort-layer construction to the entire brand.
How the Premier Hybrid is built
The Premier is a one-sided hybrid with a zippered cover and an interchangeable comfort layer. Beneath the quilted surface, DLX lists a 3-inch Premier Performance foam layer, transition foam and either a 6- or 8-inch pocketed-coil unit, depending on the profile. The manufacturer lists at least 789 coils in a Queen, with narrower-diameter coils along the edges. A coil count is a description of the build, not a test of edge strength or longevity.
The removable comfort layer is the feature that separates this purchase from a sealed fixed-feel mattress: if the initial feel is unsuitable, contact DLX about available comfort solutions. Ask which layer can be changed, whether replacement layers cost extra, how shipping works and whether the original layer must be returned. Do not assume every future adjustment is free.
DLX identifies its listed comfort foam density as 2.4 lb per cubic foot and publishes densities for other foam layers. Density can help compare the material specification, but firmness, thickness, usage and the rest of the construction matter too. A density number cannot tell you exactly how long a mattress will feel comfortable.
Choosing a firmness and split setup
DLX’s own scale places Soft at 2, Medium at 4, Medium-Firm at 6 and Firm at 8 out of 10, with 10 being firmest. Those are the manufacturer’s labels, not measurements from Yawnder or scores directly interchangeable with another brand. Use them to start a conversation about your present mattress and preferences.
If you sleep on your side, consider how much room your shoulder and hip need to settle. If you spend most of the night on your back or stomach, check that the surface supports your midsection without feeling uncomfortably hard. A partner with a different body size may experience the same layer differently.
An internal split can provide different firmnesses within one mattress. Ask which bed sizes permit the combination you want, whether there is a noticeable transition in the middle and what each person should do if their side needs adjustment. This is different from two separate Twin XL mattresses on a split adjustable base; independent movement requires a compatible setup.
For a deeper model comparison, see our Premier Hybrid guide, LatexLux review and two-sided Classic review. Compare the exact materials and care instructions rather than treating all DLX models as interchangeable.
Choosing firmness and profile
Side sleepers: Start by discussing shoulder and hip cushioning with DLX. Body weight and how deeply you settle matter more than the word “medium” alone.
Back and stomach sleepers: Check whether the firmness choice keeps your pelvis from settling farther than you prefer. A taller version is not automatically firmer or more supportive for your body.
Couples: Internal split firmness can be useful when partners want different surfaces. Ask how the layers meet and what adjustment support is available. Internal split comfort does not establish that each side can articulate independently on an adjustable base.
120-night trial: understand the refund process
DLX’s trial details specify 120 days from delivery and at least 30 nights of use before working toward a comfort solution or refund. Eligibility is limited to the original purchaser and one refund per household. Stained, damaged or unsanitary mattresses, special-order sizes and several other exclusions do not qualify.
The important logistical detail: DLX says it does not take mattress returns or remove the mattress from your home. Its refund process requires donation and proof that the mattress has been removed. Contact DLX for its instructions before arranging disposal or removing labels; keep law tags intact during normal trial use.
If local charities will not accept a used mattress, ask DLX how that situation is handled before purchasing. Read the return policy alongside the trial page. A trial is only useful if you can complete its requirements.
Before you order: height, support and delivery
Measure from the floor to the top of your current bed and compare it with the 12- or 14-inch Premier plus your base. The extra height changes the way you get in and out and may require deeper fitted sheets. Confirm that the frame is the correct size and that its slats or platform meet DLX’s current support requirements; photograph the foundation and keep the receipt with your order details.
If you need an adjustable base, ask DLX about compatibility for the selected configuration and verify the base’s weight rating for the mattress and sleepers. Our adjustable-bed weight guide explains the load calculation. For delivery, confirm the route into the room and whether setup or old-mattress removal is included.
Before deciding, compare the full delivered price at the same size and firmness with alternatives. Include any foundation, setup, protection and potential layer-adjustment charges. The ability to change comfort is useful only if you understand the available options and costs.
Lifetime warranty versus comfort assurance
The limited warranty covers specified defects, including qualifying impressions greater than 1.5 inches. In the first 10 years DLX describes repair or replacement without a mattress charge, excluding transportation or disposal costs; later coverage is prorated. Normal firmness changes and preference changes are excluded.
Comfort Assurance is a separate discounted replacement program: a same-type, size and style replacement at 50% off the current retail price, excluding promotions, with transportation costs paid by the purchaser. It is not a free lifetime exchange or a promise that the mattress never wears out.
Frequently asked questions
Can the Premier Hybrid be flipped?
Do not assume so because DLX sells a double-sided collection. Follow the care instructions for your exact model.
Does adjustable firmness mean an adjustable air mattress?
No. The Premier listing describes an adjustable foam comfort layer. Ask DLX about the physical adjustment process and any replacement-layer costs.
Which height should I buy?
Compare the actual layer specification, total bed height and sheet fit. More height alone is not proof of a better personal match.
Can I change the feel after buying?
The Premier has an interchangeable comfort layer. Contact DLX about eligible options, timing and any costs before ordering; the warranty and trial are separate from layer adjustments.
Does split firmness mean split movement?
No. Different internal firmnesses do not by themselves make the two sides move independently on an adjustable base.
Will DLX pick up a mattress I want to return?
Its published trial says it does not remove the mattress. Contact DLX first for current donation and documentation instructions.
Our recommendation: Consider Premier for its comfort flexibility, then confirm support requirements, adjustment help and donation logistics in writing before ordering.
