5 Best Memory Foam Mattress under $700 (November 2026)

Memory foam has a reputation problem: some people love the slow-sinking hug, others wake up feeling like they slept in warm sand. If you are searching for the best memory foam mattress under 700 dollars, you have probably already decided that cushioning and pressure relief matter more than bounce, and the real work is separating mattresses that are mostly foam from hybrids, toppers, and thin dorm-style pads that carry the same label. A shopping list at this price should deliver a full mattress in a box, not a two-inch layer you drop on top of an old one.

This guide is for side sleepers who want shoulder and hip cushioning, couples who dislike feeling each other move, students moving into a first apartment, and anyone replacing a sagging spring bed on a budget. Only genuine mattresses made of or built around memory foam are covered here, which leaves five options for 2026, spread across twin, full, queen, and king sizes. Toppers and protectors that appeared in the search results were set aside because they are not mattresses.

How to Choose

Thickness and what it hides

For an adult, look for 10 inches or more, with 12 inches being the common sweet spot for a bed in a box. An 8 inch model like the Zinus twin is appropriate for lighter sleepers, children, bunk beds, and guest rooms, but heavier adults may push through the comfort layers to the base. Thickness alone does not guarantee quality, so look for the construction notes in the listing, such as the number of foam layers, the type of base, and whether the cover zips off. A thick mattress with a flimsy base foam can sag sooner than a thinner one with a denser support core.

Firmness and sleep position

Medium or medium firm suits most back and stomach sleepers, because it limits how far the hips sink. Side sleepers who want more cushioning around shoulders often enjoy a medium feel. A mattress that is too soft can leave you stuck in a hollow, while one that is too firm loses the pressure relief you shopped for. Body weight changes the equation: lighter sleepers sink less and may find medium firm feels firmer than described, while heavier sleepers often do better with a thicker, firmer build.

Heat, gel, and hybrids

Traditional foam can trap warmth. Gel infusion, thermal balancing, and pocket springs underneath are three ways manufacturers try to move heat away. A hybrid like the VERHOPE offers more airflow and a bouncier edge than all-foam designs, though it blurs the line between memory foam and innerspring.

Certifications and cover design

CertiPUR-US and OEKO-TEX stand for foam and fabric standards on emissions and harmful substances, and fiberglass-free construction matters if you intend to wash or unzip a cover. A removable cover is a convenience for allergy sufferers. Expect an initial smell from compressed foam that fades after a day or two of airing. Also look at what budget models trim: thin base foam, no handles, short warranty terms, and low-density comfort layers that develop body impressions earlier than denser foam.

The 5 Best Options

GAESTE Full Size 10 Inch Cooling Gel Memory Foam Mattress

The GAESTE suits people sleeping in a full-size bed, such as a single adult in a smaller room, a guest room, or a student apartment where a queen would be too wide. The listing cites a 10 inch height, cooling gel memory foam, a medium feel, pressure relief and ergonomic support, plus a removable breathable cover with an anti-slip element, a practical detail for keeping the mattress from sliding on a slatted frame.

• Strength: gel-infused foam is aimed at sleepers who run warm.
• Strength: a removable, breathable cover makes refreshing the surface easier.
• Trade-off: 10 inches is a bit thinner than the 12 inch models in this group.

Skip it if you are a heavier sleeper who wants maximum depth, or if you need queen or king width for a shared bed.

VERHOPE 12 Inch Queen Medium Firm Memory Foam Hybrid

VERHOPE combines memory foam with individually wrapped pocket springs, which makes it the best match in this list for couples who want some bounce along with the cushioning. The listing also names reinforced edge support and motion isolation, features that matter if one partner gets up early or likes to sit on the side of the bed to tie shoes.

• Strength: pocket springs and a reinforced edge give more support at the perimeter.
• Strength: motion isolation is listed, which suits restless partners.
• Trade-off: it is a hybrid, so the feel is less enveloping than an all-foam mattress.

Skip it if you want the classic slow-sink feeling of pure memory foam or have a strong preference for fully foam construction. Anyone who has disliked the sensation of springs under a foam layer in the past should treat this as a hybrid first and a memory foam bed second.

Novilla King Size 12 Inch Memory Foam Mattress

The Novilla is the only king-size mattress on this list, so it is the obvious pick for a primary bedroom with space for a wide bed. The listing mentions a 12 inch profile, pressure relief, and thermally balanced foam intended for heat dissipation, which speaks to the main complaint about foam: sleeping hot. The extra width also gives pets and partners their own territory.

• Strength: king width gives couples and pets plenty of room.
• Strength: thermally balanced foam addresses heat buildup.
• Trade-off: a king mattress in a box is bulky and heavy to move into a room.

Skip it if your bedroom, stairway, or frame cannot handle king dimensions, or if you prefer a hybrid feel. The weight of a king box also means two people may be needed to carry it upstairs, so measure doorways and turns before ordering.

Zinus Memory Foam 8 Inch Green Tea Mattress, Twin

Zinus is the classic budget-conscious name here, and this twin suits kids, dorms, bunk beds, and spare rooms. The listing mentions an 8 inch height, pressure-relieving comfort, full-body support, a naturally fresh Green Tea infusion, and both CertiPUR-US and OEKO-TEX certifications. Its light twin size is easy to carry up a dorm stairwell.

• Strength: certifications offer reassurance for a child or guest bed.
• Strength: slim profile fits frames with limited clearance.
• Trade-off: 8 inches is thin for heavier adults or daily use by a side sleeper.

Skip it if the bed is for a large adult every night or you need a bigger size than twin. It is also not the right pick for a long-term master bedroom, where a thicker mattress with more comfort layers gives more room before sleepers reach the support base.

KOW 12 Inch Queen Memory Foam Mattress

KOW pitches a queen mattress in a box with a washable removable cover, a medium firm feel, and fiberglass-free construction. It is the pick for allergy-minded shoppers or households with kids and pets, where the ability to wash the cover can be worth more than a fancy cooling name. Parents and dog owners tend to value being able to launder the top layer, and the medium firm label points to a supportive feel without a deep sink.

• Strength: the washable removable cover simplifies upkeep.
• Strength: fiberglass-free construction is listed, a worry for some buyers.
• Trade-off: the visible text offers no cooling features beyond the foam itself.

Skip it if you sleep hot and want gel or hybrid airflow. Anyone expecting a cooling story will find none in the visible title.

Which One Fits Your Situation

You share a queen bed and one partner moves a lot

The VERHOPE 12 Inch Queen Hybrid lists motion isolation and edge support, which helps both sleepers. If your partner snores or turns over at night, a mattress that keeps that movement from traveling across the surface can mean fewer interrupted nights, and the pocket springs should also make getting out of bed easier on the knees.

You run hot at night

The Novilla King, with thermally balanced foam, or the GAESTE Full, with cooling gel, are the two most heat-conscious picks, depending on the size you need. Neither listing publishes a temperature figure, so treat the cooling language as a design intention and combine it with breathable sheets and a lightweight blanket for the best result.

You are furnishing a kids room or guest room

The Zinus 8 Inch Twin is the practical option, with certifications and a slim profile, and it is easy to move when the room is rearranged or the bed changes owners. Parents often pair it with a waterproof protector, a separate purchase that extends the life of any foam bed in a kids room.

You have pets, children, or allergies

The KOW Queen, with its removable washable cover, makes spills and routine cleaning easier to manage, which is a real advantage when the bed is shared with children or a dog.

Common Mistakes

• Buying a topper when you need a mattress, since a two to three inch pad cannot replace a failing base.
• Ignoring size, then discovering the full or twin you ordered does not match the bed frame.
• Choosing the softest feel for a back or stomach sleeper who needs hip support.
• Judging the mattress on night one, before the foam has fully expanded and the smell has faded.
• Overlooking certifications and cover design when buying for a child or an allergy-prone sleeper.

Frequently Asked Questions

How long does a boxed memory foam mattress take to expand?

Most reach their shape within a day, though some manufacturers suggest up to 72 hours. Leave the room ventilated, because new foam can have a mild odor, and wait until the mattress is fully expanded before judging the firmness.

Is a hybrid still a memory foam mattress?

A hybrid uses memory foam over pocket springs, so you still get contouring, plus extra bounce and airflow. It is a good middle ground if all-foam feels too enclosing, and it explains why a hybrid can feel bouncier and sleep cooler than its all-foam neighbors, even though both mention memory foam in the title.

Which firmness is best for side sleepers?

Many side sleepers prefer a medium feel, since it cushions shoulders and hips. Heavier sleepers may find medium firm more supportive, while stomach sleepers should lean firmer to keep the hips from dipping below the shoulders.

Do certifications such as CertiPUR-US matter?

They show the foam meets standards for emissions and certain substances. They are a helpful tiebreaker, especially for children, but they do not tell you how a mattress feels.
