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
Sealy's Ortho Memory Mattress is an excellent option for those wanting to have a supportive, comfortable mattress that doesn't break the bank. Using all of Sealy's vast knowledge and experience, this mattress is incredible value for money and will leave you refreshed and well-rested each morning.
Sealy has provided the very best possible specification to every element of this mattress. From the supportive foam that forms the core of the mattress to the smart-fibre cover that keeps you cool and comfortable at all times, Sealy has built a superb mattress, and so it is no surprise that this mattress is one of our top sellers.
The high-density foam at the core of this mattress is designed to offer support and stability at all times. Providing a good level of support is paramount for a mattress, without it the body sinks into the mattress too much and pressure points begin to form (the main cause of aches and pains in the morning). This Sealy mattress has a deep layer of foam that will ensure you're supported at all times.
Not only is this a deep layer of foam, but the foam itself is Zoned. There are certain areas of the body (hips and shoulders) that focus more weight into the mattress, and by supporting those areas more accurately and precisely, the body will have better posture and those aches and pains will be further prevented. A clever technique with big results!
On top of the supportive foam core, Sealy has added a deep layer of luxurious Memory Foam. This deep layer is truly sumptuous and compliments the supportive layer perfectly. This delicate layer of soft feeling foam is like the icing on the cake, topping the mattress with a supremely comfortable layer.
The Sealy Ortho Memory mattress has been finished in a tactile, soft, knitted fabric that looks as good as it feels. Finished to a high standard, this mattress has also been treated with a Purotex fibre infusion, that will prevent the growth of bugs and bacteria, ensuring it remains fresh and comfortable throughout its long life span.
This Sealy Ortho Mattress is delivered rolled up. Please allow up to 4hrs for the mattress to fully expand, although it may appear ready quickly. This is a no-turn mattress, but we recommend rotating it once per Season.
