What is a medium firm mattress?

A medium firm mattress is a sleep surface that falls in the middle of the firmness scale, providing a balanced level of support and comfort for individuals who prefer a mattress that is not too soft or too firm. A medium firm mattress is rated a ‘3’ on our scale of firmness, with 1 being softest and 5 being the firmest.

What's the best medium firm mattress?

The best medium firm mattress for you will depend on your specific preferences. We offer everything from small singles to super king size medium firm mattresses with memory foam, pocket sprung and natural filling mattresses available. One of our most comfortable medium firm mattresses is the 5’0″ King Size Bamboo Breathe 6000 Mattress. With its large size and combination of 6,000 pocket springs alongside a memory foam layer make it an incredible comfortable medium firm mattress.

Is a medium firm mattress good for side sleepers?

Yes, a medium firm mattress can be a good option for side sleepers. Side sleeping is a common sleep position, and it can put pressure on the shoulders and hips if the mattress is too firm. However, a mattress that is too soft can lead to improper spinal alignment, which can cause pain and discomfort over time. A medium firm mattress provides a balance between support and comfort, and it can help keep the spine aligned while also providing enough cushioning to relieve pressure points.

Is a medium firm mattress good for your back?

Yes, medium firm mattresses can be good for your back. A medium firm mattress can provide a balance between support and comfort, which can help keep the spine in proper alignment while also cushioning pressure points.
