In detail

The Mammoth Ascend in detail

The Mammoth Ascend is the middle Mammoth range, for couples and anyone who wants solid sides. It takes the Mammoth Elevate and adds an extra firm PostureCell edge and a premium support layer, with seven spring zones in place of five. It is Australian made with a 15 year maker's guarantee.

What makes the Mammoth Ascend different

  1. PostureCell Medical Grade edge support

    An extra firm edge of PostureCell foam runs around the comfort layer to reduce roll out and add integrity to the sides, and it is castellated so air can move through and keep you at a comfortable sleep temperature.

    You can lie right up near the side of the bed without it giving way under you, and the sides stay ventilated while you sleep.

  2. Premium support layer

    A layer of high density premium foam sits over the springs, firm in the Ascend 4, medium in the Ascend 5 and plush in the Ascend 6, and it gives a stable, supportive surface that contours to your body.

    You choose how firm the bed feels by choosing the 4, 5 or 6, and the rest of the build stays the same across all three.

  3. 7 zoned nested pocket springs

    The nested springs are split into seven zones where the Mammoth Elevate has five, softer under the shoulders and firmer under the hips and lower back.

    The support changes in more steps along your body, so your shoulders can settle in while your hips and lower back are held up and your spine stays in line.

  4. 3 zone PostureCell Medical Grade foam

    The comfort layer is PostureCell, a Medical Grade foam developed in UK healthcare that contours to your body without needing heat, with cooling air flow channels running through it.

    You feel comfortable as soon as you lie down, whichever position you sleep in.

  5. Probox edge support

    Below the PostureCell edge, a 90mm wide Probox side support of Ultra-Fresh treated Dunlop foam runs around the springs, which gives the Ascend two edge systems working together.

    You get an edge to edge sleeping surface without roll out, from the comfort layer right down to the springs.

Who the Mammoth Ascend suits

  • Couples

    The extra firm PostureCell edge and the 90mm Probox edge give the Ascend two edge systems, so both of you can use the bed right out to its sides.

  • People sensitive to pressure

    The seven zone springs are softer under your shoulders and encourage the mattress to contour to you, which the maker says suits people with pressure sensitivity.

  • People who sleep warm

    The Fast Temp cover helps keep you dry and comfortably cool, air flow channels run through the PostureCell layer and the castellated edge lets air move through the sides.

  • Anyone on an adjustable base

    The Mammoth Ascend is listed to suit an adjustable base, so it can go on one of the adjustable beds from our range.

What you pay for

A price on a screen does not tell you how a mattress feels, and it does not tell you what happens if it is wrong for you. Here is what actually separates buying here from buying online.

Try before you buy

You lie on it here first, on the showroom floor at 35 Altin Street, so you know how it feels before you pay for it.

Local support after

Any question is a phone call or a visit, not a freight booking, because we are around the corner in Griffith.

Questions about this mattress

From the top down it is a Fast Temp fabric cover, a layer of natural wool, quilting foam and 3 zone PostureCell Medical Grade foam with an extra firm PostureCell edge around it, then a premium support layer in firm, medium or plush, all sitting on 7 zoned nested pocket springs with a 90mm Probox edge around the perimeter.

The Ascend comes in 4, 5 and 6, which are firm, medium and plush, and the premium support layer sets the feel with high density firm foam in the 4, medium in the 5 and plush in the 6. The 4 suits sleepers who prefer a stronger, more supportive feel, the 5 is the balanced option and the 6 gives more cushioning and pressure relief, so come in and lie on it at 35 Altin Street before you choose.

The Ascend has an extra firm PostureCell edge around the comfort layer and a premium support layer that sets the feel, and the Mammoth Elevate has neither. Its springs are split into seven zones where the Mammoth Elevate has five, and the Mammoth Infinity keeps all eight of the Ascend's elements with the springs in nine zones.

It is an extra firm edge of PostureCell foam around the comfort layer that reduces roll out and adds integrity to the side of the mattress. It is castellated so air can move through the sides and keep you at a comfortable sleep temperature, and it sits above the 90mm Probox edge around the springs.

The Mammoth Ascend comes with a 15 year maker's guarantee.

Yes, it is listed to suit an adjustable base, so you can pair it with an adjustable bed from our range.

Yes, the Mammoth Ascend is Australian made. The Mammoth brand itself was founded in the United Kingdom.
