by The Aireloom Arpeggio Plush is a 14.5-inch plush innerspring built for side sleepers who want a deep, cushioned top over wrapped coils, and it is a store-bought luxury bed, not an online trial buy. You would buy it for the build: an air chamber above the spring unit, seven comfort foams, a Tencel and phase-change knit, silk and wool in the quilting, and 842 wrapped coils in the Queen. You would think twice about the money side: Queen is $3,999.99 at Mattress Warehouse today, the trial is a one-time exchange with no refund, and the 120-night comfort exchange only applies if you live within 30 miles of one of their stores.
How we compared
This page uses the retailer’s product listing, the retailer’s trial, return and delivery policies, and Aireloom’s published warranty card. I did not sleep on this model for this article and did not measure firmness, surface temperature, motion transfer or edge support. Sleep-position advice below follows the comfort level the listing advertises.
What you are buying: a hand-built innerspring with an air chamber on top
The Arpeggio is an innerspring mattress with a Plush comfort label and a 14.5-inch profile. Aireloom builds it around a natural chamber that sits between the spring unit and the mattress top, so the comfort layers float above the coils instead of being packed flat against them. That chamber is the height of the bed, and it is the first thing to picture when you compare it with a dense foam mattress you sink into rather than rest on.
The support unit is specific: 8-inch Support-flex tempered 13 3/4-gauge individually wrapped coils inside a high-density foam-encased perimeter. The published spec for this model gives 842 coils in the Queen and 1,052 in the King. Wrapped coils move independently, which is the standard way to cut partner disturbance in a spring bed, and the foam rail around the edge is what keeps the sleep surface usable right up to the border.
Above that sit seven named comfort materials: plush quilting foam, plush convoluted foam, firm quilting foam, cotton tricot backing, plush CopperGel foam, luxury firm Aireluxe foam and visco elastic memory foam. The listing states the memory foam is CertiPUR-US certified. The top itself is an ultra-conforming knit with Tencel and phase-change material, paired with a breathable blend of silk and wool fibers and FR fibers edge to edge.
Two of those names do real work: CopperGel foam is positioned as a heat-dissipating layer, and the luxury firm Aireluxe foam is the durable layer meant to keep your spine aligned under the softer materials. The listing tags the mattress Cooling and Pressure Relief, and lists side as the intended sleep position.
Every size, every price
Here is the full size list with both numbers, because a sale price only means something next to the number it came from. The $200 saving sits on top of a free-gift promotion.
| Size | List price | Price shown | Saving |
|---|---|---|---|
| Twin (38 x 75 in) | $3,699.99 | $3,499.99 | $200 |
| Twin XL | $3,899.99 | $3,699.99 | $200 |
| Full | $3,999.99 | $3,799.99 | $200 |
| Queen (60 x 80 in) | $4,199.99 | $3,999.99 | $200 |
| King (76 x 80 in) | $5,299.99 | $5,099.99 | $200 |
| California King | $5,299.99 | $5,099.99 | $200 |
| Split California King (1 pc) | $3,899.99 | $3,699.99 | $200 |
Every size is 14.5 inches tall, so measure the gap at your headboard before you order and check that your sheets still fit the deep profile. The sister chain, Sleep Outfitters, lists the same Queen at $3,999.99 from $4,199.99, so the promotion is chain-wide rather than a single-store markdown.
How firm is it, and which sleep positions suit it?
There is no numeric firmness score for this model, so the starting point is the label: Plush, with side named as the intended position. Based on that advertised comfort level, here is how I would read it:
- Side sleepers: the first position I would put this bed on your shortlist. A plush surface over an air chamber is designed to let the shoulder and hip drop in while the coils carry the midsection, and the listing itself points at side sleeping.
- Back sleepers who like a soft hug: reasonable, but you are buying a plush bed. If you want your lower back held up rather than cradled, this is the wrong comfort label.
- Stomach sleepers: not the bed to start with. A soft top lets the hips sink, and a 14.5-inch plush build gives them plenty of room to do it.
- Couples: wrapped coils and a foam-encased edge are what usually keep one partner’s movement from crossing the bed.
My practical advice: this is a showroom mattress first. Mattress Warehouse lists an in-store “Try Before You Buy” option, and a few minutes on the exact Arpeggio in your own position beats any firmness adjective, including mine.
The trial, the return and the warranty: the part that decides a $4,000 purchase
This is where the Arpeggio stops being a normal online buy: no 100-night refund window from the brand, just a retailer’s exchange policy and a manufacturer’s warranty card. Both are written documents, and the headline is more generous than the detail.
| What the trial actually gives you | Mattress Warehouse / Sleep Outfitters |
|---|---|
| Comfort window | 120 nights |
| Minimum before you can act | 30 nights of sleep on it |
| Refund? | No. All sales final once delivered or picked up |
| What you get instead | A one-time exchange, credited at 100% of what you paid toward a replacement of equal or greater value; you pay any price difference |
| Fees on that exchange | $99 delivery plus $29.99 per piece removal |
| Conditions | A mattress protector bought with the mattress; exchange within 120 days of delivery; law tags attached; mattress clean and sanitary |
| Who is eligible | Residents within a 30-mile radius of a store |
Read that table twice before you buy. The exchange is one-time, it excludes foundations, adjustable bases, pillows, protectors and frames, and it returns credit rather than cash. If you buy this bed and simply want your money back, the retailer’s return policy does not do that: mattresses are final sale once delivered, cancellations before shipping must come within 24 hours, and a cancellation after shipping can carry a 20% handling fee plus the shipping cost.
The warranty: the code on your law label decides everything
Aireloom’s warranty card does not publish one term for every mattress. It prints a chart of warranty codes, and the code is on the white law label stitched to your mattress. The non-prorated window is 10 years on every A code, which is the part that matters most: after that, a prorated year still costs you a share of a replacement.
| Code on the law label | Total limited warranty | Non-prorated | Prorated | Impression called normal |
|---|---|---|---|---|
| A1 | 10 years | 10 years | None | 1.5 in or less |
| A2 | 10 years | 10 years | None | 0.75 in or less |
| A3 | 15 years | 10 years | 5 years | 1.5 in or less |
| A4 | 20 years | 10 years | 10 years | 1.5 in or less |
| C1 | 5 years | 5 years | None | None |
Aireloom’s registration page describes a 10-year guarantee for all its products, while the card’s chart runs to 15 and 20 years on two codes; the 10-year non-prorated stretch is common to all of them, and the code on your mattress decides which line you own. The warranty runs to the original purchaser with the original receipt, and transportation on a warranty claim is yours to pay, prepaid. Queen and King need a heavy-duty frame with proper center support, and on a slatted base the slats must be no more than 2 inches apart. A slatted base that lets the mattress sag between slats can cost you the coverage. The card also tells you to rotate after the first two to four weeks and then through the break-in period, and asks you to register within a month of purchase.
Delivery, and what arrives at your door
On orders over $999 the retailer advertises free white glove delivery and setup: the crew brings the mattress to the room of your choice, sets it up, removes the packing materials and gives you a three-hour window confirmed the night before, with the delivery itself free if they miss it. Old-mattress haul-away and recycling is a separate $29.99 per piece, and stained items cannot be taken for biohazard reasons. Outside the delivery footprint, fees of up to $299 can apply, and the service does not reach P.O. boxes, Alaska, Hawaii or Puerto Rico.
The listing also carries a Lifetime Price Guarantee, narrower than the name sounds: an adjustment is limited to what you originally paid, excludes taxes, delivery fees and promotional incentives, and applies only while the identical make, model and size is still made and sold by the retailer.
What owners say about this exact listing
The Mattress Warehouse listing carries an average of 2.5 out of 5 from 6 ratings. Six ratings is too small a sample to judge a $4,000 mattress on, and the sibling chain shows no score at all, but this is the only owner score attached to the model on the page you would buy it from.
How the Arpeggio compares
Start with the brand: our Aireloom mattress review covers what the collections share and where they differ, and Aireloom’s custom mattress review looks at the made-to-order side of the range. For the brand-versus-brand question, Saatva vs Aireloom runs that face-off with trial and warranty terms side by side.
The retailer’s own comparison row puts three rivals next to this bed, and they are the ones to lie on the same afternoon:
- Sealy Posturepedic Elite Brenham Soft Euro Pillow Top: a soft euro pillow top innerspring at 16 inches, the shortest of these three.
- Beautyrest Black Series Four Plush Pillow Top: also plush, at 17.25 inches, with a motion-separation tag the Arpeggio does not carry.
- Stearns & Foster Reserve Soft Pillow Top: the closest in luxury positioning, 17 inches, with an eco-friendly tag of its own.
The Arpeggio’s counter-punch is the chamber construction and the silk-and-wool quilting: none of those three describes its top as an air chamber over the spring unit.
Who should not buy it?
- Skip it if you want firm. The label is Plush and the listing points at side sleeping. Do not buy a soft luxury top expecting a flat, rigid surface.
- Skip it if you might want your money back. There is no refund path: all sales are final once delivered, and the 120-night policy is an exchange with a $99 delivery fee and $29.99 per-piece removal.
- Skip it if you live outside the 30-mile radius of a Mattress Warehouse or Sleep Outfitters store. Outside it, the comfort guarantee does not apply and you are buying a showroom-type bed without the showroom safety net.
- Skip it if your foundation is a problem. Queen and King need a heavy-duty frame with center support, and a slatted base must have slats no more than 2 inches apart or the warranty suffers for it.
- Skip it if you are shopping on price alone. This is a $3,499.99-to-$5,099.99 innerspring; a mattress-in-a-box at a quarter of that money will still be a mattress.
- Skip it if you need a boxed delivery. This one arrives by white glove with setup, which is a plus for most buyers and a deal-breaker if you wanted to carry it up yourself.
Frequently asked questions
Is the Aireloom Arpeggio Plush a hybrid?
No. The listing classifies it as an innerspring: individually wrapped coils with foam comfort layers above them, not a foam core with a coil layer.
How tall is it, and will my sheets fit?
14.5 inches in every size, so deep-pocket sheets. Check the total height against your headboard and box spring before you order.
How much does it cost?
Queen is $3,999.99 and King $5,099.99, each $200 under list, with a free-gift promotion alongside. Sizes run from Twin at $3,499.99 to California King at $5,099.99.
Can I return it for a refund?
No. Mattresses are final sale once delivered or picked up. What you can do inside 120 days, after 30 nights of sleep, is a one-time comfort exchange with a $99 delivery fee and $29.99 per-piece removal, credited at the full amount you paid toward a replacement of equal or greater value.
How long is the warranty?
Between 10 and 20 years depending on the code printed on your law label, with a 10-year non-prorated period in every case. Transportation on a claim is yours, and the mattress needs proper support to stay covered.
Does it sleep cool?
The listing tags it Cooling and credits a Tencel and phase-change knit, CopperGel foam and a silk-and-wool blend for airflow. Those are the brand’s materials descriptions, not a temperature measurement, so the honest answer is that the build is designed for heat dissipation and no one publishes a degree figure for it.
Is it certified?
The visco elastic memory foam is described as CertiPUR-US certified. Aireloom’s OEKO-TEX Standard 100 announcement covers the Preferred Collection, and the Arpeggio is not among the models listed on the brand’s own product pages. The dealer’s paperwork is where that question gets settled for this mattress.
Where can I buy it?
Mattress Warehouse stocks it online and in stores, its sister chain Sleep Outfitters lists the same Queen price, and the page carries an in-store “Try Before You Buy” option. Aireloom sells through authorized dealers rather than direct from the brand.
Bottom line: buy it for the build, buy it near a store
The Arpeggio Plush is a genuinely well-specified innerspring: air chamber, seven comfort layers, silk and wool in the quilt, 842 wrapped coils in a Queen and a foam rail around the edge, and if you are a side sleeper who likes a soft, deep top, it deserves a place on your showroom shortlist. Queen at $3,999.99 puts it in serious luxury territory, and the free white glove setup makes the delivery side painless.
The ownership terms are what I would weigh just as hard: no refunds, a one-time exchange, a $99 fee to use it, a 30-mile radius and a foundation requirement you have to meet to keep the warranty. Buy it within driving distance of the store, put a protector on it the day it arrives, and ask for the law-label warranty code before you sign.
