King size pocket sprung mattresses

Is a pocket sprung king size mattress good for couples?

A pocket sprung king suits most couples: each person gets 75 cm of width, and because every spring moves on its own, each side responds to the person lying on it rather than to the whole bed.

Two people make more heat than one, and air moves through the springs, so a pocket sprung king usually sleeps cooler than an all-foam one. Many have firmer edges too, which gives you a steady place to sit and helps stop the side dipping when one of you sleeps near it. At 200 cm long, a king also suits sleepers up to about 185 to 190 cm tall.

Pocket springs do pass on a little more movement than memory foam. If that's what wakes you, compare our king size memory foam mattresses.

How many springs should a king size mattress have?

No set number of springs makes a king size mattress good, but kings are one of the sizes spring counts are most often quoted for, so on a king a figure such as 1000 is more likely to describe the mattress you're actually buying.

Even so, compare more than the number. More springs in the same space means each one is narrower, and very high counts such as 2000 often include a second layer of small springs near the surface, so two mattresses with the same figure can be built quite differently. Wire gauge matters as well: thicker wire feels firmer, and a lower gauge number means thicker wire. The comfort layers and fillings above the springs decide how the surface feels. See pocket sprung mattresses in every size.

Pocket sprung or memory foam for a king size?

For a king size bed, pocket springs suit couples who run warm, sit on the bed a lot or like a springy, responsive feel, while memory foam suits light sleepers who are woken by movement.

A hybrid puts a foam comfort layer over pocket springs, for couples who want some of each.

Are pocket sprung king size mattresses heavy?

Pocket sprung king size mattresses are heavy, because a 150 x 200 cm mattress holds a lot of steel springs, and many can't be rolled, so they're delivered flat and wrapped. A flat king needs no time to recover, but it's a two-person carry.

Before you order a flat one, measure the route to the bedroom: the narrowest doorway, the landing and the tightest turn on the stairs. If the route is tight, choose a king that arrives rolled; each mattress page says which. Most of our mattresses can be delivered the next working day; read delivery and returns before you order. The weight matters again whenever you rotate the mattress, so make that a two-person job as well.

Is a pocket sprung king good for heavier people?

A pocket sprung king is a sound choice for heavier sleepers, who usually need firmer support, a deeper mattress, a strong spring unit and firm edges, and a well-built pocket sprung king can offer all four.

For two heavier sleepers, think about your combined weight, choose a deep mattress of 25 cm or more, and look for medium-firm or firmer. Firm edges count for more here, because the side of the mattress takes your full weight every time you sit down to get in or out. A king also gives each of you 7.5 cm more width than a double. Check any maximum weight guidance on the product page, and see our mattresses for heavier people for more choice.

We're a family-run shop and glad to talk through firmness, depth or stair measurements before you buy, so get in touch, or compare all our king size mattresses.
