Experts at Wedo Mattresses feel that Zero Deflection Posturetech Spring System manages to deliver the qualities of an ortho mattress plus support tailored to your movement at an affordable price. In addition to offering great support, the Firm Ortho is durable and being traditionally hand tufted adds to its longevity.

The firm nature of the Firm Ortho mattress means it is ideal for those seeking a mattress to provide back support. Pressure Knockout Zones help to prevent tossing and turning and provide targetted support to the lower back, where you need it most.

Its luxurious damask fabric and traditional hand tufting ensure comfort isn't compromised despite its durability. Furthermore, this mattress has hypoallergenic properties, which assist in protecting allergy and asthma sufferers from harmful allergens.

Customer reviews




This is seriously firm, been looking for something for ages but not found anythign in the shops that did the job, this does.

Pete (29/11/2012)
Actually firm




I generally stay away from branded products because I find you end up paying for the label rather than the product but the price of this mattress seemed very reasonable. It is genuinely firm which makes a nice change as I have found the descriptions of things like firmness to be a bit hit or miss before. Would buy a Sealy mattress again anyway, this one has been just as described and at a good price as well.

Sealy simply the best




Sealy are the best, had one of their mattresses before but I think it has gone out of production and this was the nearest I could find. It is just as good as the last one, hopefully it will last as long as my previous one. Site was really easy to use as well.
