Best Oversized King Quilts For Deep Mattresses: Top 5 Picks Compared

Finding an oversized king quilt for a deep mattress is about more than choosing a larger size label. The quilt’s actual dimensions determine how far it hangs over the sides and foot of your bed, while its fabric, weight, and construction affect how it works as everyday bedding. These five options range from extra-wide 120-inch designs to breathable cotton and plush velvet styles. Compare the measurements with your mattress and foundation before choosing, especially if you want to cover a tall bed without a bed skirt.

Our Picks: Best Oversized King Quilts For Deep Mattresses reviews

1. Love’s cabin Oversized King Quilt Set: Extra-Wide, Lightweight Coverage

At 120 by 120 inches, this Love’s cabin set offers one of the largest square footprints in this group. That extra fabric can help cover the sides of a deep mattress and provide a generous drop over the foot of the bed. Your final coverage will still depend on the mattress, foundation, and how the quilt is centered.

The quilt is made from brushed polyester and uses ultrasonic pressing to create its embossed coin pattern without traditional stitched quilting. It is designed to be lightweight and easy to move under, which may suit warm sleepers or anyone who prefers less weight on the bed. Use it on its own in warmer weather or layer it over a blanket or comforter when you need more warmth.

The bluish-grey solid color is fairly easy to coordinate with other bedding. The set includes the quilt and two 20-by-36-inch shams. Its light construction is a practical choice for a guest room or a bed used by children or pets, but polyester will feel different from the natural cotton option below. If a highly textured, stitched look is important to you, this pressed pattern may not be your first choice.

Pros:

• Generous 120-by-120-inch size for broad coverage
• Lightweight design works well for layering or warmer nights
• Includes two matching pillow shams
• Solid color and embossed pattern are easy to style

Cons:

• Polyester fabric may not suit shoppers who prefer cotton
• Ultrasonic-pressed texture differs from traditional stitched quilting

Verdict: Choose the Love’s cabin set if your main goal is a lightweight, extra-wide quilt with a simple look and plenty of fabric to drape over a deep king bed.

2. Bedsure Velvet Oversized Quilt: A Plush, Dressy Bed Topper

This Bedsure option stands out for its brown velvet surface, natural sheen, and channel quilting. It is described as a lightweight all-season bed covering that can be used alone in warmer weather or layered when you want more warmth. The set includes two 20-by-36-inch shams, and the quilt is listed as machine washable and dryer-safe.

There is an important sizing detail to check before buying: the product title gives a measurement of 113 by 96 inches, while the description gives 113 by 106 inches. Because a difference of 10 inches can change the drop on a deep mattress, confirm the dimensions shown on the listing before ordering. The description also calls it both a California king quilt and a comforter, so check the product details to make sure its size and style match your bed.

The velvet finish makes this a stronger choice for shoppers who care about a soft, decorative surface as much as coverage. Its dimensions, whichever listing figure applies, are less straightforward than the 120-by-120-inch options in this guide. Measure your mattress and foundation carefully if you want the quilt to reach close to the floor or cover the sides of a particularly tall bed.

Pros:

• Velvet fabric adds a plush look and feel
• Channel quilting is designed to keep the fill in place
• Includes two matching pillow shams
• Machine washable and dryer-safe according to the product description

Cons:

• Product title and description give different quilt dimensions
• Not as wide as the 120-by-120-inch options listed here

Verdict: Consider this quilt if you want a velvet finish, but verify its listed dimensions first, particularly if full coverage on a deep mattress is your priority.

3. EVENHUG Oversized King Bedspread: Reversible Pattern and 120-Inch Coverage

The EVENHUG bedspread measures 120 by 120 inches and is designed for extra-wide California king beds, split kings, and beds with thick mattresses. Its generous dimensions make it one of the more adaptable choices here if a standard king-size coverlet leaves too much mattress exposed. The set comes with two 20-by-36-inch shams.

Made from microfiber, the quilt has a leaf-and-rose pattern and a reversible design. Its quilting is intended to help limit shifting of the filling, while the product description says the fabric is wrinkle-resistant and can be machine washed in cold water and dried at a low temperature. It arrives compressed, so washing or low-temperature ironing may help remove packaging wrinkles.

This is a practical pick if you want a patterned bedspread that can work as a light summer layer or sit over a comforter in colder weather. The 120-inch square shape gives you a lot of fabric, but it may be more coverage than you need on a shorter or lower bed. Check how far you want the quilt to hang and whether you want it to cover the bed skirt before choosing this size.

Pros:

• 120-by-120-inch dimensions suit many wide or tall beds
• Reversible design offers two ways to style the bed
• Microfiber construction is described as wrinkle-resistant
• Can be used alone or as a layer over other bedding

Cons:

• The generous size may be too long or wide for some beds
• Microfiber may not be the preferred feel for cotton bedding fans

Verdict: Pick the EVENHUG set if you want a reversible patterned bedspread with substantial coverage for a wide, split, or deep mattress.

4. Davulos Deep Purple Oversized Quilt: Bold Color with Geometric Texture

The Davulos set pairs a deep purple color with a reversible geometric pattern. Its quilt measures 106 by 118 inches, and the set includes two 20-by-36-inch shams. The microfiber fabric is described as lightweight, breathable, and soft, making this a possible choice if you want a substantial bedspread without a heavy feel.

The quilt uses ultrasonic embossing for its two-sided geometric texture. According to the product description, the construction is intended to limit filling shifts and handle frequent household washing. It is designed for year-round use: on its own in warmer weather, or as an outer layer over warmer bedding in winter.

The product description says this size drapes to the floor on beds 21 to 24 inches tall and hangs neatly on beds 26 to 30 inches tall. Those results depend on how the quilt is positioned and on your mattress and foundation measurements, so use them as a guide rather than a guarantee. Compared with the square 120-by-120-inch options, this quilt is narrower, but its 118-inch length may provide a useful drop at the sides and foot of some beds.

Pros:

• Distinctive deep purple color and reversible geometric pattern
• Microfiber is described as lightweight and breathable
• Listed as suitable for tall beds, including beds with deep mattresses
• Includes two matching pillow shams

Cons:

• Color may be harder to coordinate than a neutral shade
• At 106 inches wide, it offers less side-to-side fabric than a 120-inch quilt

Verdict: Choose the Davulos set if you want a richly colored, textured quilt and its 106-by-118-inch dimensions provide enough drop for your bed.

5. EVERGRACE Cotton Channel Quilt: Breathable, Natural-Fiber Bedding

For shoppers who prefer natural fibers, the EVERGRACE set is made with 100% cotton fabric and fill. The cotton is prewashed for softness, and the quilt has a simple channel-stitched design in cocoa brown. It is also described as using responsibly sourced BCI Cotton and carrying OEKO-TEX STANDARD 100 certification.

The quilt measures 110 by 92 inches and comes with two 20-by-36-inch shams. That size is smaller than the 120-by-120-inch options in this guide, so take extra care to compare it with your mattress and foundation before buying. On a very deep or wide bed, it may not provide the same side coverage as the larger sets.

This quilt is intended for year-round layering: use it as a lightweight cover in warmer weather or add it over other bedding when you need more warmth. The product description says it is machine washable and dryer-friendly. Its simple channel design makes it a lower-key alternative to the patterned and velvet choices, but its more limited dimensions make fit the main consideration for deep mattresses.

Pros:

• 100% cotton fabric and fill
• Prewashed for a softer feel
• Clean channel stitching and neutral cocoa-brown color
• Machine washable and dryer-friendly according to the product description

Cons:

• Smaller dimensions may provide less drop on a deep king bed
• Lightweight construction may need another layer in colder weather

Verdict: Choose the EVERGRACE quilt if breathable cotton matters most and its 110-by-92-inch size gives your mattress the coverage you want.

How to Choose an Oversized King Quilt for a Deep Mattress

Measure the Bed Before Choosing a Size

Measure the mattress width, length, and height, then include the foundation or box spring if the quilt needs to cover it. To estimate the side drop, subtract the mattress width from the quilt width and divide the result by two. For example, a wider quilt usually hangs farther on each side, but the final result also depends on whether you tuck it in, how it sits on the bed, and how much of the foundation you want to cover.

Compare the Actual Dimensions, Not Just the Size Name

Terms such as “oversized king” and “California king” do not guarantee the same measurements across products. Look for the listed width and length, and check that they suit your mattress shape. One product in this group even gives conflicting dimensions in its title and description, which is a good reason to confirm the details on the product page before ordering.

Consider Your Mattress, Foundation, and Bed Height Together

A quilt that covers the mattress alone may not hide a tall foundation or bed frame. If you want the quilt to reach close to the floor, measure from the top of the mattress to the point where you want the edge to fall. Also account for pillow placement and any bedding layers underneath, which can affect how the quilt drapes.

Choose a Fabric and Weight That Suit Your Sleep Habits

Microfiber and polyester options in this guide are described as lightweight and easy to layer. The cotton option may appeal if you prefer natural-fiber bedding. Velvet offers a more plush, decorative surface. Think about whether you run warm, want the quilt to work as a summer cover, or plan to use it mainly as a top layer over a warmer comforter.

Check the Construction and Care Instructions

Quilting, stitching, and ultrasonic embossing give a quilt its texture and help hold its filling in place. The products here use different methods, so choose the look and construction you prefer. Check the care directions too: some descriptions specify cold washing and low-temperature drying, while others note that the quilt is machine washable and dryer-safe.

Decide How Much Coverage You Actually Want

Extra-wide bedding can cover a bed skirt, hide the sides of a tall mattress, or create a generous drape. But the largest option is not always the best fit. A quilt with too much fabric may hang lower than you want or need more adjustment when making the bed. If possible, compare the product dimensions with a quilt you already own and like.

Look at the Whole Set, Not Just the Quilt

Each set listed here includes two pillow shams, but the fabric, pattern, and dimensions vary. Consider whether you want a solid color, a reversible print, velvet, or cotton, and whether the included shams suit your pillows. If you use specialty-size pillows, check the sham measurements before purchasing.

Frequently Asked Questions

What size quilt should I get for a deep king mattress?

Start with your mattress and foundation measurements rather than the size label. Compare the quilt’s width and length with the bed, then work out how much drop you want on the sides and at the foot. A 120-by-120-inch quilt offers more fabric than the 110-by-92-inch EVERGRACE option, but the right choice depends on your bed’s dimensions and your preferred drape.

Will an oversized king quilt cover a bed skirt?

It may, but coverage depends on the quilt dimensions and the height of your mattress, foundation, and frame. Measure from the top of your mattress to the bottom edge you want covered, then compare that measurement with the quilt’s expected drop.

Is a 120-by-120-inch quilt suitable for a California king bed?

It may work for some California king beds, but check the quilt’s length and width against your mattress. California king and standard king mattresses have different proportions, and the fit also changes with mattress depth and foundation height.

Can I use an oversized quilt on a split king or adjustable bed?

Some oversized quilts can cover the full width of a split king, and the EVENHUG description specifically lists split king beds as a possible fit. If you raise or adjust the two sides separately, consider whether one large quilt will move or bunch as the bases change position.

Are these quilts warm enough for winter?

Most of these options are described as lightweight or suitable for layering. They can be used over a warmer blanket or comforter in colder weather, but the product details do not provide a common warmth rating for comparison. If you need substantial insulation, plan on adding a separate layer.

Which option is best if I want cotton?

The EVERGRACE set is the cotton choice in this group. Its description lists 100% cotton fabric and fill, with a 110-by-92-inch quilt. Measure your bed carefully because it is not as large as the 120-by-120-inch sets.

What should I do if a product listing gives two different sizes?

Confirm the dimensions in the current product details before buying. This matters especially for the Bedsure option, whose title and description give different measurements. If the sizing remains unclear, do not assume the larger figure will apply to the item you receive.

Final Recommendation

For the most generous listed dimensions, the Love’s cabin and EVENHUG quilts both measure 120 by 120 inches, making them strong starting points for shoppers who need extra coverage. Choose Love’s cabin for a simple, lightweight embossed design, or EVENHUG for a reversible patterned bedspread. The Davulos set offers a distinctive color and geometric texture, while EVERGRACE is the clear cotton option. Bedsure may suit shoppers drawn to velvet, but its conflicting size details make it especially important to verify the measurements before ordering.
