What will we do with your old bed/mattress?
We will do one of three things:
- A local charity may want it. We have given them many items in the last year
- We may recycle the mattress
- Some mattresses cannot be recycled, and so we use a local disposal service to take care of the goods.

Product Description
The Sealy Hamilton mattress is part of the new Enhance Collection, a range of beds designed by Sealy to offer excellent comfort and support at a great price. This range of beds has a 1000 Pocket Spring system at its core and a Gel support layer on top. This Hamilton mattress is the mid-range model and is a medium firmness mattress.
Sealy are famous the world over for their quality and comfort and are one of the very few bed makers that have genuine science behind the specifications of their mattresses. This Hamilton mattress is no different and will benefit those who prefer a medium firmness level (ideal for front or back sleepers).
The 1000 pocket springs at the core of this mattress will move down as weight is applied, perfectly and instantly mirroring the contours of the body, preventing aches and pains through the promotion of great posture. Each spring is wrapped in its own fabric pocket, so it cannot interfere with surrounding springs when moving, which means the support is absolutely uncompromised!
On top of this no-turn mattress is a Gel layer. Gel has been used by Sealy in this range as it is luxuriously comfortable, breathable and very durable. The comfortable nature of Gel means it is the perfect material to use alongside the pocket springs, which is where the support comes from. These two aspects combine to make a medium tension in this Hamilton mattress. The breathable Gel will allow air to move freely through the mattress, keeping it cool and comfortable at all times. This is further complemented by the breathable fabric used to wrap this mattress.
We deliver the Sealy Hamilton mattress to you for FREE (some geographical charges may apply) with our 2-person delivery crews!

Pocket Springs
Sealy has incorporated a 1000-pocket spring system at the core of the Hamilton mattress. These springs move up and down seamlessly as your body shifts during the night, promoting good posture and helping to prevent aches and pains that can result from inadequate support.
No Turning
This is a no-turn mattress, so you'll only ever need to spin it around, not flip it over. We deliver to the room of your choice for you, and we'll place the mattress on the bed, so you'll never need lift it! Sealy recommends rotation of the mattress every 3 months.
60 Night Trial
As with all our mattresses, you can buy with confidence thanks to our sleep trial. If you are not completely happy with the Hamilton mattress after 60 nights, just let us know, and you can swap it for any other mattress on our website. T&Cs apply.
