Soft King Size Mattress FAQs

Find answers to common questions about our products

A king-size soft mattress can be excellent for many sleepers, particularly those who prefer a plush, contouring surface, combined with plenty of space to move around. 

Soft mattresses are ideal if you're a side sleeper, as they allow your hips and shoulders to sink in slightly. This is great for maintaining proper spinal alignment. They're also beneficial for lighter-weight individuals who may not compress firmer mattresses enough to feel comfortable.

Yes, soft mattresses are particularly well-suited for side sleepers. 

When you sleep on your side, your body creates pressure points at the hips and shoulders, where it naturally curves.

A soft king-size mattress allows these areas to sink in comfortably, reducing pressure and maintaining proper spinal alignment.

Soft king-size mattresses measure 150cm x 200cm (5ft x 6ft 6in), providing plenty of space for couples or individuals who enjoy extra room to stretch out.

Our soft king-size mattress range is designed to fit standard UK king-size bed frames and bedding, making them a perfect upgrade for your existing bedroom setup.

Our hybrid mattresses combine the best features of different mattress technologies, featuring a layer of memory foam over a core of individually wrapped pocket springs. 

Hybrid mattresses offer the pressure relief and contouring of soft materials with the responsive support and breathability of spring systems.

Our options also include cooling gel hybrid mattresses, which incorporate gel-infused memory foam to help regulate temperature throughout the night.
