PULSIO THERMASLEEP REVIEW

PULSIO THERMASLEEP COOLING AND HEATING MATTRESS TOPPER SYSTEM

PLEASE NOTE: I paid for the Pulsio Thermasleep myself and was not gifted this product by Pulsio to give a honest review. This page contains affiliate links. Making a purchase via our affiliate link means I may receive a small share of the sale.

The Pulsio Thermasleep system is a budget friendly, water cooled and heated mattress topper that lets you set different temperatures for each side of the bed, offering an accessible alternative to premium systems like Eight Sleep for sleepers.

It skips the heavy “smart” features in favour of straightforward, manual temperature control at a much lower price point.

The Pulsio Thermasleep is perfect if you overheat at night or argue over the bedroom thermostat, giving each sleeper their own controllable climate zone.

It sits on top of your existing mattress and uses a compact water unit to actively cool or warm your bed throughout the night.

WHAT IS THE PULSIO THERMASLEEP SYSTEM?

Pulsio Thermasleep is a smart, water pod mattress cover that circulates temperature controlled water through thin channels to maintain your chosen sleep temperature.

It is positioned as a more affordable, simpler competitor to high end sleep tech like Eight Sleep, focusing on comfort rather than in depth sleep tracking.

WHAT IS INCLUDED?

I bought the super king Thermasleep with dual side control and includes:

• The mattress topper cover that fits over your existing mattress.
• 2 x water pod units that heats or cools the circulating water.
• Hoses and connectors to link the pod to the cover
• Power cables
• 2 x controllers
• Quick start guide and basic maintenance instructions for filling, flushing and descaling the system.

If your opt for single or full coverage you will only have 1 water pod and 1 controller.

PLEASE NOTE: You need to buy distilled water to fill the pods. I bought this distilled water from Amazon.

HOW DOES IT WORK?

Thermasleep works by pumping cooled or heated water from the pod through channels in the mattress cover, absorbing excess body heat when set to cool and adding gentle warmth when set to heat.

Because it actively maintains the set temperature all night, it can be more consistent than relying on room heating, fans or passive cooling mattresses.

We previously had an portable air conditioning unit in our bedroom in the summer months and whilst it was great at keeping us cool, it was noisy and left you with a dry throat.

By putting the Thermasleep to its lowest setting it keeps you cool enough even on hot summers nights.

DOES IT COOL AND HEAT BOTH SIDES?

The Thermasleep cover is available in dual zone versions that let you set one side of the bed cooler and the other warmer, so couples can sleep at different temperatures.

Each side has its own controllable zone, which is a core part of the appeal for partners who sleep “hot” and “cold” in the same bed.

My wife likes to have her side nice and warm during the winter, where as I like to have a steady cool temperature so I don't overheat.

For me this is probably the best feature about the system.

WHAT SIZES ARE AVAILABLE?

The system is designed to fit common bed sizes such as Double, King and Super King, and works with “any mattress”. You do not need a specific mattress for it to go on.

This makes it suitable for fitting your existing mattress without changing your current bed setup.

Ours fitted over our super king Simba mattress perfected. 

HOW LONG DOES IT TAKE TO WORK?

The system begins to noticeably change the bed temperature within 5 to 10 minutes, with the mattress surface reaching a comfortable range fairly quickly after you switch it on or adjust it.

We typically turn it on 30 minutes before getting ready for bed, so it feels ready as soon as you lie down.

A CHEAPER EIGHT SLEEP ALTERNATIVE?

Pulsio is pretty much a quarter of the price of the cheapest Eight Sleep system.

However compared with Eight Sleep’s Pod systems, this is because Thermasleep focuses on manual temperature control and leaves out advanced features like sleep stage tracking, AI‑driven auto adjustments and integrated health metrics.

Eight Sleep offers app based smart automation, snoring and elevation features and detailed sleep analytics at a much higher price, while Thermasleep is a budget friendly, non smart option that simply keeps each side of the bed at the temperature you set.

HOW MUCH IS IT?

The Pulsio Thermasleep system starts at £449.99 depending on if you choose single, dual or full bed configuration and which size you choose.

I bought the super king dual control system, which was £719.99.

WHERE TO BUY?

You can buy the Pulsio thermasleep direct from the Pulsio website.

CONCLUSION

For runners who want a reliable temperature control and dual zone comfort without spending four figures, the Pulsio Thermasleep system is an appealing, pragmatic choice.

It cannot match Eight Sleep’s smart tracking and automation, but as a more affordable, straightforward way to stop overheating or shivering at night, it represents strong value for money.
