King mattresses are the most expensive size category — and therefore the category where clearance savings are most significant in absolute dollar terms. A 30% discount on a $2,000 king saves $600, while the same percentage off a $700 queen saves $210. If you’re in the market for a king, understanding how to find clearance deals is even more valuable than it is for smaller sizes.
Why King Clearance Is Different
King mattresses make up a smaller percentage of overall mattress sales than queens, which means clearance inventory in king sizes is less abundant. The upside is that when king clearance does appear, it’s often at deeper discounts than queen clearance — retailers need to move the inventory and have fewer king shoppers to sell to.
Split kings (two twin XLs placed together, popular with adjustable base setups) represent an additional consideration — their clearance pricing and availability differ from standard kings.
King Mattress Clearance by Price Tier
Genuinely capable king mattresses under $500 at full price are rare, but clearance and sale pricing can surface options in this range. Zinus and Linenspa king models at clearance pricing (particularly through Amazon Warehouse) occasionally reach $300–$400 territory. These are appropriate for guest rooms or secondary applications rather than primary sleep surfaces expected to last a decade.
$500–$900 King
This range represents the best clearance value for king shoppers. At this budget during sale events, quality foam and entry-level hybrid options from established brands become accessible. Nectar’s holiday events bring their king (which retails around $799) into the $600–$700 range with bundles included. Tuft & Needle king pricing falls similarly during their major events.
$900–$1,500 King
For shoppers willing to invest in a quality primary sleep surface, king clearance in this range surfaces legitimately excellent hybrids. Helix’s king models retail around $1,299 and drop meaningfully during holiday events. Brooklyn Bedding’s Signature Hybrid king retails around $1,199 with stacking coupons pushing under $1,000. Casper and Purple holiday pricing for king sizes regularly enters this range from higher standard pricing.
$1,500+ King (Luxury Clearance)
Saatva’s outlet and WinkBed’s holiday events occasionally surface premium king options in the $1,200–$1,800 range — mattresses that standard retail for $2,000–$3,000. For shoppers who want luxury construction in a king size, monitoring these brands’ clearance channels is the highest-leverage approach.
King-Specific Shopping Considerations
Measure your bedroom first. A standard king is 76″ x 80″ — larger than queen by 16 inches of width. Confirm your bedroom can accommodate a king with appropriate clearance around the bed before committing to a clearance purchase (which may have limited or no return options).
Foundation costs. King mattresses require king foundations or platform beds. If you’re buying new bedding infrastructure alongside the mattress, factor foundation costs into your total budget. Some clearance bundles include foundations, which can meaningfully increase total value.
Split king for adjustable bases. If you’re using an adjustable base, you’ll need two twin XL mattresses rather than a standard king. Clearance pricing on twin XL sizes varies significantly from king pricing — verify sizing requirements for your specific adjustable base setup before shopping.
Best Timing for King Clearance
Memorial Day and Black Friday consistently produce the deepest king mattress discounts. Retailers and brands know that shoppers who are already committed to the higher spend of a king purchase are motivated buyers — the sale events reflect this with competitive pricing. Setting aside budget and timing a king purchase around one of these events is the clearest path to maximizing value at this size.

Where to Find the Best King Mattress Clearance Events
King-size mattress clearance deals appear most reliably at large national chains like Mattress Firm, Ashley HomeStore, and Macy’s, where high sales volume creates regular turnover in floor model inventory. These retailers run structured clearance events tied to seasonal promotions, giving savvy shoppers predictable windows to access the deepest discounts. Mattress Firm’s clearance section, available both in-store and online, regularly features king-size models at 40–60% below original retail pricing.
Independent mattress retailers are another strong source of king clearance deals, particularly in metropolitan areas. Independent shops often carry a curated selection of premium brands and discount their floor models aggressively when updating their showroom lineup. Building a relationship with a local independent retailer and asking to be notified when king-size clearance items become available can give you first access before items are advertised publicly.
Online clearance sections from direct-to-consumer brands have expanded significantly in recent years. Saatva’s clearance page, Purple’s outlet section, and WinkBed’s last chance listings all regularly feature king-size models at meaningful discounts. These online clearance purchases typically include full delivery service, making them competitive with in-store options even after factoring in any shipping fees.
Timing Your King Mattress Clearance Purchase
The timing of a king mattress clearance purchase can make a significant difference in the final price. The largest mattress clearance events of the year are concentrated around major holidays: Presidents’ Day in February, Memorial Day in May, Labor Day in September, and Black Friday in November. These events typically layer additional promotional discounts on top of existing clearance pricing, creating the deepest annual discounts of anywhere from 50–70% off original retail on select king models.
End-of-year is also a strategic time to shop for king clearance. Retailers are motivated to clear remaining inventory before the new year, and December often brings strong deals particularly on models that didn’t sell through during the Black Friday promotional window. January clearance events following holiday promotions similarly offer good selection as stores reorganize their showroom floors for the new year.
Avoiding peak shopping periods like the immediate run-up to major holidays can also work in your favor. Arriving at a clearance event a day or two before the official start date sometimes allows you to negotiate early access with store management, particularly if you’re prepared to purchase without waiting for the promotional pricing to go live officially.
Evaluating King Clearance Mattresses for Durability
King mattresses represent a larger investment than smaller sizes, which makes durability evaluation more important before purchase. The key indicators of a durable king-size mattress in a clearance context are the same as for any size but matter more given the higher price point. Look for a coil count of at least 1,000 individually wrapped coils in a queen equivalent — king-size models should scale this upward proportionally, with 1,200 or more being a good threshold for a hybrid king.
Foam density in the comfort layer is another key durability indicator. Memory foam layers rated at 4 PCF or higher tend to hold up longer than lower-density alternatives, particularly in the king size where the greater sleeping surface is under frequent use from two sleepers. Polyfoam comfort layers should be at least 1.8 PCF to avoid premature compression, with 2.0 PCF or higher being preferable for long-term performance.
The cover fabric also provides clues about overall construction quality. Tightly woven cover fabrics — particularly those using Tencel, organic cotton, or wool blend materials — indicate a manufacturer that invested in quality throughout the mattress. Loosely woven or thin cover fabrics on clearance models may signal cost-cutting that extends into the internal materials as well.
Managing Delivery and Setup for King Size Clearance Purchases
The logistics of delivering a king-size mattress require more planning than smaller sizes. Standard king mattresses measure 76 inches wide by 80 inches long, which can present challenges for narrow hallways, stairwells, and doorways. Before completing a clearance purchase, measure the path from your front door to the intended bedroom to confirm a king-size mattress can be maneuvered through without damage.
Most major retailers offer white-glove delivery that includes setup in your room and removal of your old mattress. Confirm whether this service applies to clearance items and what the fee structure is. Some retailers include white-glove delivery in the mattress price; others charge $50–$150 as an add-on. For king-size mattresses specifically, white-glove delivery is worth paying for because the size and weight make DIY setup genuinely difficult without help.
Compressed-in-a-box king mattresses from direct-to-consumer brands are typically delivered via standard freight or courier service in a large box, which is easier to manage than an unboxed mattress on a truck. The compression process does make king mattresses manageable for one or two people to move, but full expansion after unboxing takes 24–72 hours and requires adequate ventilation in the room during that time.
Pairing Your King Clearance Mattress With the Right Foundation
A king-size clearance mattress at a great price can lose its value quickly if placed on an inadequate foundation. Box springs designed for king mattresses provide perimeter and center support, but older box springs with worn or broken internal structure can accelerate sagging and void the mattress warranty. If your existing box spring is more than 7–8 years old, consider replacing it as part of your clearance purchase budget.
Platform bed frames with slats are a popular alternative to box springs for king mattresses. Ensure slat spacing is no more than 3 inches apart and that the frame includes at least two center support legs that reach the floor. Without adequate center support, a king-size mattress — particularly one with foam layers — will develop a sag in the middle under the weight of two sleepers over time.
Adjustable bases are compatible with most king-size foam and hybrid mattresses and represent an excellent upgrade to pair with a clearance mattress purchase. Many retailers bundle clearance mattresses with adjustable base discounts, creating an opportunity to access both a quality mattress and a premium foundation at a combined price well below what either would cost at full retail.
Final Tips for Securing the Best King Mattress Clearance Price
Getting the absolute best price on a king clearance mattress requires both preparation and the willingness to act decisively when a good deal appears. Research specific models in advance so you know the original retail price and can quickly calculate the actual discount percentage of any clearance offer. A 40% discount on an originally $2,000 mattress is a better deal than a 50% discount on a mattress that retailed for $900 — knowing the baseline prices prevents you from being misled by percentage claims alone.
Don’t hesitate to negotiate, particularly at brick-and-mortar stores. Floor managers almost always have some pricing flexibility beyond the marked clearance price, especially for king-size models that take up significant showroom floor space. Expressing genuine interest and willingness to purchase that day gives you the strongest negotiating position.
Finally, always factor in the total cost of ownership, including any delivery fees, foundation upgrades, and mattress protectors needed to complete your setup. A king clearance mattress priced at $600 with a $150 delivery fee and a $100 foundation upgrade costs $850 total — still likely excellent value, but important to calculate accurately before comparing options across different retailers.
