When it comes to the best mattress for couples, our top choice is the Amerisleep AS3 mattress with its balanced medium feel. As a whole, Amerisleep focuses more on different firmnesses that suit different needs instead of trying to accomplish the impossible task of creating a mattress perfect for everyone.That said, the AS3 mattress comes close to providing near-universal comfort. The mattress's mix of plant-based memory foam and targeted support can support sides, back, or combination sleepers with various body types.The AS3 has three foam layers encased in a soft, breathable cover fabric. The first layer is Bio-Pur? memory foam, a material made with plant-derived oils and traditional synthetic ingredients. Because of its special makeup, Bio-Pur? foam stays cool and responds faster than traditional memory foam.Next is the transition layer, Affinity foam with HIVE? technology. Hexagons are cut with precision to establish five distinct zones across the surface of the Affinity foam. The hexagonal cutouts in the shoulders and hips are arranged to increase flexibility, while the cutouts in the head, torso, and feet promote support.Last is a layer of Bio-Core? foam, a sturdy material that keeps the mattress from developing soft spots or sagging.The Amerisleep AS3 mattress includes free shipping, a 100-night sleep trial, and a 20-year warranty. With a lengthy sleep trial, you have a few months to try out the mattress at home and can return the bed for a full refund if you're not satisfied. The warranty protects against potential defects, including sagging that exceeds 0.75 inches.Best Memory Foam King Size Mattress: Zoma Mattress

The Zoma Mattress has a design that goes beyond cooling features, focusing on restorative recovery and implementing unique technologies that help a person sleep deeply and undisturbed.The first layer of cooling and conforming gel memory foam moves absorbed heat away, preventing build-up. Otherwise, sleepers could potentially wake up prematurely feeling overheated and sweating. Memory foam also eliminates pressure points by molding to the body's curves.The pressure-relieving capabilities of Zoma's gel memory foam are also boosted by the included Triangulex??? technology. Triangular cutouts are placed in the mattress's head and foot, leaving the midsection cut out free. These cutouts help the mattress flex with the sleeper's body, increasing the cushion under the head, shoulders, and legs. Plus, the cutouts double as air channels for greater heat dispersion.Underneath the gel memory foam is a layer of Zoma-exclusive material known as Reactiv???. This foam is designed to mimic the bounce of latex without the associated cost, creating a more responsive surface to limit sinkage and entrapment. Reactiv??? makes it easy to move across the mattress's surface.Last is the appropriately named base layer of Support+ foam, a material that provides the mattress with stability and longevity. The sturdy foam keeps permanent impressions from developing, preventing soft spots and sagging.Purchase of a Zoma Mattress includes a 100-night sleep trial and a 10-year warranty.Best Affordable King Size Mattress: Vaya Mattress

For many people living on a limited budget, buying a king size mattress can seem like an unattainable dream. While it's not impossible to find an inexpensive king size mattress, it is challenging to find one that provides durable comfort and support. That's why our top recommendation for a mattress with high value is the Vaya Mattress.When we discuss value, we're referring to how much you pay for the mattress vs. how many years of comfortable sleep you can expect. Vaya keeps the costs down by arranging top-shelf materials in a simple design that still maximizes their potential.The Vaya Mattress has two layers of foam. There is a responsive comfort layer followed by a supportive base layer.The Vaya Comfort Foam is lighter than traditional memory foam and engineered to conform to the body in all sleep positions. The base foam takes on the body's weight and distributes it evenly to limit pressure build-up while supporting the spine's alignment.Because of its medium feel versatility, we recommend the Vaya Mattress for all sleeping styles. The bed feels plush but not too plush, giving sleepers a luxurious sleep surface that doesn't break the bank.Every Vaya Mattress includes a 100-night sleep trial and a 10-year warranty.

Adjustable beds are the secret behind many sleepers' comfort. For example, people who snore or have sleep apnea often sleep better when they raise their upper bodies. An adjustable bed is one of the better ways to do so.Similarly, split king mattresses can help couples sleep better at night while still allowing them to share a bed. So when it comes to king size comfort, it's difficult to beat the possibilities that an adjustable bed with a split king mattress offers. Our top recommendation for a king size adjustable bed bundle is the Ghost Bed Split King Adjustable Bed Set.One of four GhostBed mattresses can be bundled with the king size adjustable bed. You can choose the GhostBed Classic or GhostBed Luxe for an all-foam mattress. If you prefer a bouncy mattress, there's the GhostBed Flex or the GhostBed 3D Matrix?. The feels of these mattresses vary, with each one suiting different sleep styles.Naturally, the biggest drawback to this bundle is the price. Purchasing one of these sets will mean making a significant investment. However, for many couples, the cost is worth the improved rest.Best King Size Mattress on Amazon: Zoma Start

- Pocketed coils buoy the body and react individually to movements
Many couples enjoy the idea of stretching on a soft, cloud-like mattress after a long day. Sleepers who desire a plush, expansive mattress should consider the bouncy Amerisleep AS5 Hybrid. Two contouring layers top a base of pocketed coils for a responsive yet cushioning surface.The AS5 Hybrid has four layers; two focused on comfort and two providing support. The top layer is what you find in all Amerisleep memory foam mattresses, Bio-Pur? foam. We mentioned the benefits of Bio-Pur? foam earlier, but just to recap, the material is designed to be more responsive and breathable than traditional memory foam.Underneath the Bio-Pur? foam is a responsive layer of Active Flex foam. Active Flex is designed to be buoyant yet contouring, improving the mattress surface without affecting the plush feel.The AS5 Hybrid's support core is a tall layer of pocketed coils on a firm foam base. Every coil inside the hybrid is wrapped to promote motion isolation, keeping a person's every movement from rippling across the surface. The coils also retract under pressure, adapting to the body's position while promoting airflow through the mattress's bottom.The foam base gives the coils a surface to push off from, helping them stand strong after years of use.Like other Amerisleep mattresses, the Amerisleep AS5 includes a 100-night sleep trial and a 20-year warranty.Who Should Sleep on a King Size Mattress?
For couples, the choice is usually between a queen or king size mattress. While the best queen size mattresses offer affordable prices and a relatively compact design, they just can't match the expansiveness of a traditional king bed. King size mattresses are excellent for partners who enjoy their personal space.Parents with small children may also prefer a king size if they plan on letting a child occasionally co-sleep with them. After all, a queen bed doesn't provide much room for a child to join their parents for comfort after experiencing a nightmare.That's not to say single adults are barred from sleeping alone on a king size mattress. Indeed, a king bed is a perfect way to complete a larger bedroom and offers a luxurious amount of sleeping space. For many solo sleepers, a king size bed is the most comfortable mattress, giving them room
