Top king size mattress options by budget and construction

The list spans sprung, foam, pocket-sprung and hybrid mattresses at the prices shown.

IKEA VESTMARKA — the lowest-priced listed option

VESTMARKA is a sprung standard king mattress listed at £179. It is the clearest choice for shoppers who want the lowest price in this comparison and do not specifically require foam or pocket springs.

IKEA VESTERÖY — a lower-priced pocket-sprung option

VESTERÖY is a pocket-sprung standard king mattress listed at £199, reduced from £249. Pocket springs respond individually, making this construction different from an open-coil or basic sprung mattress.

IKEA VALEVÅG — pocket springs at a modest step up

VALEVÅG is another IKEA pocket-sprung king mattress, listed at £229 and reduced from £299. It gives shoppers a second pocket-sprung option above VESTERÖY.

IKEA ÅBYGDA — lower-priced foam

ÅBYGDA is a foam standard king mattress listed at £279. It suits shoppers who specifically want a foam feel while spending less than the Emma Original example.

Emma Original — medium-firm five-layer foam

Emma Original is 25 cm deep, medium-firm and made with five layers. Its documented construction and medium-firm feel make it the clearest named foam option in this comparison.

IKEA ÅNNELAND — a listed IKEA hybrid

ÅNNELAND is a hybrid standard king mattress listed at £699. A hybrid combines springs with foam or other comfort layers, offering an alternative to an all-foam or traditional sprung mattress.

Simba Hybrid — a higher-priced hybrid option

Simba Hybrid is listed at £999 for a UK king. It is another hybrid choice for shoppers comparing a branded model with IKEA’s £699 ÅNNELAND.

King size mattress types: memory foam, pocket sprung or hybrid?

Memory foam contours to the body, pocket springs respond individually, and hybrids combine springs with foam or other comfort layers. UK king-size ranges also include traditional springs, latex and gel mattresses.

  • Memory foam: choose this construction if you want a foam feel and body-contouring comfort. Emma Original and IKEA ÅBYGDA are examples in this guide.
  • Pocket sprung: choose this if individually responding springs are important. IKEA VESTERÖY, VALEVÅG, VÅGSTRANDA and VATNESTRÖM are listed pocket-sprung models.
  • Hybrid: choose this if you want springs combined with comfort layers. IKEA ÅNNELAND and Simba Hybrid are examples.
  • Traditional sprung: IKEA VESTMARKA is the lowest-priced example in the comparison.

Mattressman categorises king mattresses from softer and medium soft through medium and medium firm to firmer and extra firm. Its guidance also connects firmness with sleeping position: softer or medium options are commonly considered by many side sleepers, while firmer options are commonly considered by front or back sleepers.

King size mattress IKEA, Emma and Simba: what to compare

IKEA UK sells UK mattress sizes rather than European sizes, and its standard king is 150 × 200 cm. A European king is 160 × 200 cm, so it is wider. Match the mattress dimensions to the bed frame.

Emma provides product-level information for Original, including its 25 cm depth, medium-firm feel, five-layer construction and listed king price. IKEA provides a broad range of constructions and prices, including sprung, foam, pocket-sprung and hybrid models. Simba provides a higher-priced hybrid alternative at £999.

Argos has a dedicated king-size mattress category that includes products such as the Habitat Elite Memory Foam Kingsize Mattress and Emma Original Classic Memory Foam Mattress. Its category is useful for browsing, although the relevant current model prices are not included here.

How to choose a king size mattress

  1. Measure the frame: confirm that it takes a standard 150 × 200 cm UK king mattress.
  2. Choose the construction: decide between foam, pocket springs, hybrid or traditional springs.
  3. Choose the firmness: use your sleeping position and personal comfort preference as starting points.
  4. Compare the mattress type and price: a low-priced sprung mattress is not directly comparable with a higher-priced foam or hybrid model.

For a king size orthopaedic mattress, do not rely on the label alone. Compare the actual construction, firmness and depth. The word “orthopaedic” does not by itself identify whether a mattress is foam, pocket sprung, hybrid or traditional sprung.
