The Summerhill FAQs

What kind of sleeper is this mattress best for?

The Summerhill is ideal for sleepers who prefer a firmer mattress with robust support. Its 7/10 firmness makes it suitable for side, back, and stomach sleepers, especially those who desire a mattress that offers substantial support without excessive sinking. The reinforced center third provides added support where it's needed most, promoting proper spinal alignment.

How firm is this mattress, and what does it feel like?

The Summerhill is rated 7/10 on our firmness scale, delivering a firm, supportive feel with just the right amount of cushioning. Its open-cell foam layers provide gentle contouring and pressure relief, while the 1100 pocket coil system offers strong, responsive support that keeps your spine aligned. This combination creates a balanced surface that’s firm yet comfortable, ideal for those who want both support and some plushness.

Is this mattress good for hot sleepers?

The Summerhill is a great option if you are looking for a breathable mattress. With a pocket coil base and open-cell foam on top, heat is transferred away from the surface closest to your body down to the open airspace below where it can freely escape. The Summerhill is also quilted with our signature Dozy poly-cotton blend exterior further disperses body heat for a cooler night's sleep.

How long will this mattress last?

With proper care, the Summerhill is designed to provide lasting comfort and support for 10-12 years. To help extend its lifespan, we recommend rotating the mattress every 3–6 months. It also comes with a 10-year limited warranty for added peace of mind.

Dozy Summer 2024

Cooler. Stronger. Yours.

At Dozy, we build every mattress around two key principles:

  • Breathability - keeps you cool and comfortable through the night
  • Durability - ensures your mattress performs for years to come

What about comfort? That part’s up to you.

Comfort is personal – the perfect firmness and feel varies from person to person. That’s why we’ve invested in real showrooms, where you can try each model and find what’s right for you.

What happens if I don't like the mattress after I buy it?

No worries - our mattresses come with a 125-night comfort guarantee. That means you’ll have plenty of time to sleep on it, adjust, and decide if it’s the right fit. If it’s not quite perfect, you can exchange it, up to two times within the trial period.
