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 Highgrove Onyx Mattress bed is targeted at those of us who prefer a softer feeling mattress. The Highgrove Onyx features a traditional 13.5 Gauge spring unit supported by a reInforced side frame to provide support as well as comfort. This is a quilted mattress with looser fillings to further add to the overall softer-feel. These fillings are breathable fibres to ensure the bed remains cool and comfortable at all times.
Highgrove are a leading manufacturer of divans, mattresses and special size beds and pride themselves on quality and affordability. Using the finest components. The Highgrove Onyx has been manufactured to a high standard and specification and offers comfort and luxury to ensure a peaceful night's sleep.
This mattress is suitable for use on all bed base options including slatted bedframes (as long as the slats are no more than 7cm apart). This is a turnable mattress, requiring both rotation and turning once per season, alternating between the two. We recommend doing this more often in the early weeks after delivery to ensure even settlement.
Headboard sold separately.
