Our top of the range, most popular, and reassuringly well reviewed topper, that can instantly transform any mattress

"We give the Naturalmat Tremendous Topper a two-thumbs up, full-marks score.... It is incredibly comfortable and you’d be hard pushed to find a more substantial one.... Everything about this topper shouts 'premium'.”

– The Independent (read the full review)

  • 1. Cashmere & Bamboo

    From the soft fleece of cashmere or pashmina goats, a luxuriant layer of insulation and breathability.

  • 2. Natural Latex

    From the sap of the Hevea rubber tree. A springy and supportive natural alternative to synthetic foams.

  • 3. Organic Wool

    Sourced from local organic farms. Traps heat when you need it and disperses it when you don’t.

The Tremendous is far from your average mattress topper. We combine the most luxurious natural materials with a level of handcraftsmanship equal to our most expensive mattresses.

We start with a core of springy, supportive natural latex, and surround this top & bottom with sumptuous cashmere and locally sourced organic wool. We then wrap these premium natural fibres in the same clever covers we use across our mattress range, which are naturally hypoallergenic and meet all safety standards without the need for any nasty chemical fire retardants.

This blend of natural materials all add up to a lofty 7cm deep topper that can transform an uncomfortable mattress, and dramatically improve air circulation to prevent you overheating at night (a particular issue with memory and other synthetic foam mattresses). Alternatively the Tremendous can simply add an extra layer of body hugging comfort to elevate your bed’s luxury to the next level.

Why Buy a Topper?

A mattress topper is essentially a very thin mattress which is placed on top of your new or existing mattress to alter how it feels.

This could be to increase breathability, to adjust the softness of your mattress, or simply to provide an added layer of comfort and opulence!

Clever Covers

​In the UK there are strict fire safety standards that mattresses & toppers must pass before they can be sold to the public. An overwhelming majority of manufacturers achieve this certification by treating their products with chemical fire retardants. ​This never sat right with us, and we worked to develop a cover fabric that met the safety requirements without the need for any chemicals whatsoever.

We are also the only mattress manufacturer to add a hypoallergenic finishing pr​ocess to our covers. We treat them with natural extracts to guarantee protection from dust mites and bed bugs - perfect for allergy sufferers, whose conditions are often triggered by these unwelcome bedfellows.

Handmade in Devon

At Naturalmat, we believe that people, not machines, make a superior, long-lasting product. Our team of craftspeople ensure every stitch, every fibre, every tufting button and every cover is painstakingly created, teased and checked. That’s why we proudly stamp ‘Made by hand in Devon’ on all of our toppers.

    The comfiest

    This mattress and topper is easily the comfiest bed I have ever slept in. The only issue is it makes me want to spend significantly more time in bed!

    Good investment and great service

    Enjoyed having it to get a ‘hotel’ luxury feel at home - had excellent service and care from the Derwent House Living team in the Witney showroom of Naturalmat.

    The icing on the cake!

    Buying online without the chance to see or feel it was always a concern especially when spending £1k! but I needn’t have worried. The team at Naturalmat talked me through each variant before I chose what was best for me. The Tremendous Topper added that extra layer of luxury and softness our new mattress needed. It arrived within the timeframe stated and we’re thrilled with it!

    Dense, thick & enough yield

    I love this topper. I use this on top of a foam mattress from IKEA and cushions filling the gap in the bigger bed frame 🙈 and this topper is thick enough that I can’t tell I’m sleeping on bits underneath.

    ✔️

    ▪️Smell of lanolin (farmy) - sadly fades away after a few days.

    ▪️dense

    ▪️firm

    ▪️not too heavy so manageable 16kg

    ▪️cooler

    ❌

    ▪️delivered by fedex - wrapped in plastic and they drop it off rolling on the floor

    ▪️unreliable delivery time (estimated 9-1pm but came much later. No real time tracking)

    ▪️4 weeks lead time if you order in-store (but upon contacting customer service they changed this to next day delivery)

    ❓

    ▪️natural latex is in fact natural and apparently doesn’t lose density over time

    Other options I’ve considered in order of most similar to Naturalmat tremendous topper (King size)

    ▪️Hastens £2990/4380 (Horsetail & Neil - most similar)

    ▪️Cocomat Atlas MATTRESS £2995 (coconut fibre, natural latex - come in two parts, 12 weeks lead time from Natuzzi with vague delivery/installation deal)

    ▪️Savoir £11045 !! (Horsetail & wool, more cushiony)

    ▪️Vispring £2215 (Horsetail & wool, felt plasticky)

    ▪️Abaca (logistically tricky to install. Didn’t try)

    ▪️Woolroom sprung topper £819 (you need to buy and keep the protector £100+ to qualify for 100 nights trial 🤔. Small print is complex)

    ▪️Panda London £130 (memory foam) This is the one I had, too hot, also the foam is made of plastic. Only the cover was made with some bamboo materials apparently. Started to lose…
