Harvia R-991 Olivine Diabase Sauna Heater Stones, Rounded, 5-10 cm, 15 kg

The Harvia R-991 is a 33 lb (15 kg) box of rounded gray olivine diabase sauna stones, 2-4 in (5-10 cm) in size. The rounded shape resembles stones from the great rapids and is meant for the top layer of a sauna heater, where it produces a gentle, soft steam and lets the water flow down to the lower layers. They work in electric heaters and wood-burning stoves.

Rounded on top, angular below

Harvia recommends angular stones for the bottom layers, especially in heaters with a smaller stone capacity, and the rounded R-991 stones for the top layer. Check your heater's manual for the right stone size and amount, and pile the stones loosely so air can circulate.

Good to know before you order

Each natural stone is unique in shape and size, so Harvia suggests buying an extra box to pick the best-fitting stones. Harvia sells these stones only together with a Harvia sauna heater or stove. Please contact us about adding a box to your heater order.

Mediriser was excellent to work with to get a custom-sized hospital mattress and bed. William kept me informed throughout the process. I will contact them directly for any of my future DME needs.

IBIS Wheelchair to Car Lift

The IBIS wheelchair to car lift was a game changer for us. My husband has been in a wheelchair for more than 40 years and we have never seen anything like this in the US and had no idea such a lift exist existed.

My guy is hemiplegic and usually able to stand pivot into the car but he broke his femur in November 2025 and had to be non-weight bearing for 3 months. He lost so much strength and ability that he could no longer do any kind of safe transfer.

Our friend found the IBIS wheelchair to car lift online and we decided to take the risk. It was worth every penny and more. Within a day of its arrival we were mobile and in and out of the car again. It is very manageable for me to operate and in our 60’s we are grateful for anything that lightens our load.

Everything arrived as advertised. Customer service was outstanding with clear communication. I was provided help to ensure my measurements were correct and was offered a few options to customize the sling. We had to get a new car right after we bought the lift and it was a good fit in the new car.

We are very pleased and highly recommend this product.

It works very well

Annetta Voigt

I love the fact it installs along the side and does not have a huge footprint. It works great lifting scooter or wheel chair. Easy to use.

Fantastic Experience from Mediriser

Fantastic experience with Mediriser! We purchased a red light therapy bed and an HBOT machine. The customer service team was incredibly responsive throughout the entire process. Even when we hit a few unexpected bumps, they completely took ownership and went above and beyond to resolve them. Highly recommended for wellness equipment!
