Unlock better sleep with Wowcher UK's exclusive offers on super king memory foam mattresses. From cooling gel-infused layers to high-density support cores, these mattresses are designed to cradle you through the night while you move minimally with a partner.


Whether you’re shopping for a spacious super king memory foam mattress or a more compact king-size option, you’ll find deals that highlight comfort, durability, and ease. Look for memory foam density, thickness, and breathable covers that help regulate temperature for all-season comfort.


Frequently Asked Questions about Super king memory foam mattresses

What is a super king memory foam mattress and who should choose it?


A super king memory foam mattress is a large sleeping surface (typically 180 cm by 200 cm in the UK) with a memory foam comfort layer that shapes to your body for pressure relief. It’s ideal for couples who want generous space, especially if one or both sleepers move during the night, thanks to memory foam’s exceptional motion isolation. Look for high-density memory foam for better support and durability, and consider a cooling top layer to prevent heat buildup.

What density and thickness should I expect in a super king memory foam mattress?


Density affects support and longevity. Common good options are 3.0–4.5 lb/ft³ for the comfort layer, paired with a robust base foam. For thickness, many super king mattresses range from 25 cm to 40 cm; thicker constructions often provide deeper contouring and longer wear, but ensure your bed frame can accommodate the height and maintain proper ventilation.

Are gel memory foam and cooling fabrics worth choosing for a super king bed?


Gel memory foam embeds cooling particles that help disperse heat, while open-cell structures and breathable covers promote airflow. If you sleep hot or share a bed with a partner who moves, these features can improve comfort and reduce tossing. Also consider a breathable mattress protector to maintain airflow and protect the surface.

Is a super king memory foam mattress good for back sleepers or people with joint pain?


Memory foam’s contouring support can help align the spine and relieve pressure on hips and shoulders, which benefits back sleepers and people with arthritis or hip/knee pain. Look for medium to medium-firm feels to balance support and comfort. If you’re unsure, a 30–35 kg/m3 density range offers durable support without excessive firmness.

Can I buy a super king memory foam mattress with a sleep trial or warranty on Wowcher UK?


Yes. Many Wowcher listings include trial periods, return options, and warranties that cover manufacturing defects. Check the listing for returns windows, whether the trial applies to the whole mattress or only to certain components, and what conditions apply for exchanges or refunds. Combine with a mattress protector and an extended warranty if offered to maximise value.

What else should I consider when buying a super king memory foam mattress?


Think about compatibility with your bed frame, slat spacing, and base support. Ensure the mattress height works with your headboard and nightstands. Review care instructions — most memory foam mattresses benefit from a breathable cover, spot cleaning, and avoiding excessive moisture. For couples, factor in motion isolation and edge support to maintain comfort along the entire sleeping surface. If you’re shopping on Wowcher UK, compare multiple listings to find free delivery, discount codes, and bundle deals with pillows, protectors, and bed bases.

Which delivery options and after-sales support come with super king memory foam mattress listings on Wowcher?


Delivery options typically include standard delivery, free delivery promotions on qualifying items, and sometimes express or next-day delivery where available. After-sales support may cover courier replacements for damaged items, easy returns during the trial window, and responsive customer care from Wowcher partners. Always confirm the exact terms at the listing and at checkout to avoid surprises.
