Best King Size Bed Frame

The Santorini Bed Frame by Saatva has an elegant, high-end platform design.

Handcrafted from kiln-dried hardwood, the frame is durable and should resist signs of wear, like warping. It can support a mattress without a box spring thanks to sturdy slats made from premium plywood. However, the Santorini can also be paired with Saatva’s Lineal Adjustable Bed Base to maintain the refined look while providing adjustable positioning, underbed lighting, and massage settings.

As an upholstered model, the headboard is covered in fabric with padding underneath. Velvet and linen fabric options are available. Made from a polyester-cotton blend, the plush velvet has a vintage flair and a slight sheen. Two colors are available: taupe and graphite. The linen is woven of flax fibers, giving it a natural hue and textured appearance. Linen is very durable, so it should hold up well.

Saatva offers a 365-night sleep trial for the Santorini. Customers are eligible for a refund of the purchase price during this period, less a $99 transportation fee. The Santorini also includes free delivery and setup, including old mattress and foundation removal. A lifetime warranty backs the frame.

The Nectar Mattress Foundation is an upholstered frame with a surprisingly affordable price-point, considering the quality materials and stylish appearance.

The foundation is made with a steel frame, solid pine, and spruce, upholstered in a gray fabric. The design features wooden slats and does not require a box spring. While the foundation can sit directly on the floor, it also comes with optional wooden legs. This may appeal to anyone who likes to store items underneath the bed. Assembly is simple and does not require tools. The platform has a 15-inch profile and comes in six standard sizes, from twin to California king.

Nectar offers a 50-night sleep trial to try out the foundation, as well as a 3-year warranty. Shipping is free for customers within the contiguous U.S.

Putting together a new bed frame can be a frustrating process, especially if small hardware components are involved. The Bed by Thuma takes a different approach to foundational construction by using Japanese joinery techniques. The rails and legs fit together with intricately shaped notches, rather than screws and washers. Two hand-tightened screws are used to keep the slats in place, but otherwise no hardware is used. Two people can easily assemble The Bed in 15 minutes, if not less.

The rails, legs, and slats are all composed of solid hardwood from trees that have been sustainably grown. The slats are also lined with a felt material derived from recycled plastic. This component is intended to muffle noise and preserve the wood over time. Each order includes The Pillowboard, Thuma’s proprietary headboard that’s upholstered in pebbled fabric and padded with soft foam. Installing The Pillowboard is also very straightforward.

The Bed has received a Greenguard certification. This indicates the product has been tested for chemicals that contribute to harmful emissions. Once ordered, the bed will arrive at your residence in three separate boxes. These boxes are quite heavy, so we suggest finding a lifting partner before carrying the bed to its destination. All orders are backed by a 100-night trial period that includes free return shipping.

The Birch Madison Bed Frame showcases a timeless aesthetic while delivering sturdy, long-lasting support. Interlocking rails made of solid wood, Swedish pine legs, and plywood slats ensure excellent overall durability. You can choose between a walnut or oak finish. Birch also lets you upgrade your order to include a matching solid wood or foam-cushioned headboard.

Thanks to a design that does not require any metal hardware, the frame is remarkably easy to assemble — our team completed the setup process in less than 10 minutes. The under-bed clearance is roughly 7.5 inches. With the headboard intact, the frame measures just over 40 inches tall — keep this height in mind to determine whether it will fit comfortably in your bedroom.

The Irving Bed Frame is reasonably priced, and Birch offers free ground shipping to customers in all 50 states. Your order comes with a 100-night sleep trial. Comparatively, many brands do not offer any sort of return period for bed frames. If you choose to keep the frame, you’ll also receive a 5-year warranty against manufacturing defects.

Customers looking for a bed frame with extra storage may want to consider Silk & Snow’s Bed Frame with Storage. The stylish and comfortable upholstered design comes with a sizeable storage drawer at the foot of the bed.

The bed frame is constructed with iron and engineered wood, making it exceptionally durable. The slats are made of poplar wood. With a 2.4-inch width and spaced 3 inches apart, the slats are designed to reduce breakage. The storage drawer spans the length of the foot of the bed and measures 51 inches x 18 inches x 8 inches for the queen size, perfect for storing items like extra clothes and linens. The bed is upholstered in polyester fabric that comes in three colors – pebble, oatmeal, and granite – to match most bedroom decor. The frame also comes in three sizes – full, queen, and king.

Silk & Snow offers free shipping to the contiguous U.S. and Canadian provinces. You can try out the Bed Frame with Storage with its 30-night sleep trial. Purchases come with a 5-year warranty.

The TEMPUR-Ergo Smart Base exemplifies the luxurious quality and thoughtful construction that has come to define Tempur-Pedic as a sleep product brand. This is one of the most advanced adjustable beds our team has tested. The base is fully customizable with a wide range of motion and loaded with a suite of high-tech features, including sensors embedded in the frame to track your personal data and help you understand your sleep patterns.

You can view your nightly metrics on the Sleeptracker-AI companion app, which is free to download and compatible with any current Android or iOS device. The app also includes coaching programs to optimize your sleep night after night. Another useful function of the app is the smart alarm, which you can program to wake you up during the lightest stage of your sleep cycle — this helps ensure you feel refreshed each morning. The automatic snore response further optimizes your sleep by raising your head whenever the sensors detect snoring.

As an adjustable bed, the TEMPUR-Ergo allows you to elevate or lower the head and feet in order to find your optimal sleep position. You can adjust the angle using a wireless remote included with your order. One notable addition to the base is a lumbar support bar, which you can lift up to 6 inches for targeted lower back support. Other features include a two-zone massage you can customize with gentle vibrations beneath your most sensitive areas, under-bed lighting to help you safely navigate your dark bedroom, and USB ports for charging your devices at night.

The TEMPUR-Ergo Smart Base’s expensive sticker price reflects its high-end design, but Tempur-Pedic sweetens the deal for shoppers with free White Glove delivery throughout the U.S. Couriers schedule an arrival date with you, then set up the bed in a room of your choice. Returns are not permitted after the point of purchase, so all sales are final, but the base is backed by a 25-year warranty that includes three years of full coverage for electrical components.
