Mattresses Coupons: 36 Verified Brands | Sep 2026

Many online mattress brands, such as Emma and Wakefit, offer a 100 night trial, because it takes a few weeks to know whether a mattress suits you. Your body needs time to adjust to a new surface, so the first few nights are a poor guide to how it will feel long term.

The trial, warranty and return terms are as important as the mattress itself. This category covers mattress brands and sleep products, from Sleepwell, Kurlon, Duroflex, Centuary, Wakefit, The Sleep Company, Sleepyhead, SleepyCat, Livpure and Springtek to Emma, GhostBed, Naturepedic, Lullaby Earth, IKEA and Urban Ladder, plus pillows and support products from Frido.

Sheets, duvets and pillows are in Bedding, and bed frames in Furniture.

What this category covers

Memory foam, latex, spring or hybrid?

Memory foam molds to your body and relieves pressure, but can feel warm. Latex is bouncier, cooler and durable, while pocket spring mattresses give support and airflow with individually wrapped coils.

Hybrids combine springs with foam or latex layers for a mix of support and comfort. They are often the most expensive but suit a wide range of sleepers.

Choosing firmness

Side sleepers usually need a softer surface so the shoulders and hips can sink in, while back and stomach sleepers usually need firmer support to keep the spine aligned. Heavier people often find firmer mattresses more supportive.

Firmness scales vary between brands, so a "medium firm" from one brand can feel different from another. Reviews from people with a similar build and sleep position help most.

How long is the trial, really?

Check the minimum period before you can return a mattress, since some trials require you to sleep on it for a few weeks first. Find out whether returns are free, whether pickup is included and whether the refund is full.

Warranties

Mattress warranties commonly cover sagging beyond a certain depth and manufacturing faults, not normal softening. Using the right base and keeping the receipt are often conditions of a warranty claim.

Foam and material certifications

CertiPUR US certification checks that foam is made without certain harmful chemicals and meets emissions limits. Organic mattresses may carry GOTS for cotton and wool or GOLS for latex.

Marketing terms such as "natural" or "eco" are not certifications. Look for the certifying body's name.

Mattress in a box

Compressed mattresses arrive rolled in a box and expand once opened. Allow them to expand fully, which can take a day or two, and air the room to clear the new foam smell.

Mattress sizes

Mattress sizes differ between countries, such as single, double, queen and king in India and the UK, and twin, full, queen and king in the US, with different measurements. Measure your bed frame and check the size chart before ordering.

When should you replace a mattress?

Many sleep organizations suggest reviewing a mattress after about seven or eight years. Sagging, lumps, waking with aches, or sleeping better elsewhere are signs it is time.

Mattress protectors and care

A waterproof, breathable mattress protector keeps out spills, sweat and dust mites, and is often required to keep the warranty valid. Rotate the mattress as the maker advises to even out wear.

Choosing the right pillow

Pillow height, known as loft, should keep your neck in line with your spine. Side sleepers usually need a higher pillow, back sleepers a medium one and stomach sleepers a low one.

Memory foam and contour pillows, such as those from Frido, support the neck, while down and fiber pillows are softer and easy to reshape.

Do you need a new base?

A mattress needs the right base to perform well and to keep its warranty valid. Slatted bases should have slats close enough together that foam cannot sag between them, and old box springs can undermine a new mattress.

Mattress toppers

A topper can soften a mattress that is too firm, or extend the life of an older one for a while. It cannot fix a mattress that is sagging in the middle, which needs replacing.

Children's mattresses

Babies should sleep on a firm, flat mattress that fits the cot with no gaps, as safe sleep guidance advises. Choose a mattress made for the cot's exact size.

When mattresses go on sale

Mattress brands run frequent sales, with the biggest around festivals, Black Friday and holiday weekends. Because discounts are so frequent, the list price is rarely what people actually pay.

Making a mattress coupon go further

Mattress coupons often stack with bundle offers, such as free pillows or protectors. Compare the final price with the trial and warranty, since a longer trial is worth more than a slightly bigger discount.
