REM-Fit is a US company that has grown rapidly. Founded in 2014 they were initially a subsection of the Protect-A-Bed company. These are well known in the industry, having a good reputation for over 30 years. They became a separate company in 2018 and have continued rapidly expanding. 

While now well known and popular in the USA they are trying to do the same in the UK. Their goal as a company is to produce well-made mattresses which aid in rest and recovery. While doing this they aim to keep the mattress at a reasonable price. 

Their range of products offered is always growing. They now offer four different mattresses, each with a similar look but designed to fill a different need and a range of sleep and bedroom accessories. Their confidence in their products’ build quality shows. Offering a 15-year warranty with all of their mattresses.

The REM-Fit 500 Ortho is a specially designed orthopaedic mattress. Designed to aid people suffering from back pain. This mattress is packed with features designed to add to its support. Like the other mattresses offered by REM-Fit, it is a hybrid, a combination of pocket springs and foam layers. It has generated a good amount of interest within the online mattress industry, having won a Which Best Buy award. 

In total, the mattress has five different layers including the cover. It certainly looks like an interesting mattress on the whole. We have broken the mattress down into layers to see what they add to the mattress alongside what it feels like to sleep on.

Construction and Materials

All foam used within REM-Fit mattresses is Certipur certified. This is an independent testing body which tests to see if the foam meets guidelines on personal health and safety and also environmental.

A good sign that this mattress is manufactured to a high standard is REM-Fits membership to the National Bed Federation. These are an independent trade group which set guidelines and standards for the UK bed industry.

The colour scheme of each of the REM-Fit mattresses is pretty similar. The only difference is the colour stripe down the side of the mattress. The 500 contouring mattress from REM-Fit does have the same colour stripe, however. The top and half of the side of the mattress have a white cover. Below this is a thick teal diagonal stripe going around the mattress. Below this is a black finish which is also on the bottom of the mattress. This black material features anti-slip properties to stop the mattress moving around on the base. This helps prevent damage to the base and mattress caused by it sliding around. Overall the style of the cover gives the mattress a very modern and stylish look. 

The REM-Fit 500 Ortho mattress is a hybrid mattress featuring a combination of memory foam. In total it features five layers including the base. We have broken down each layer to investigate what it adds to the mattress.

1. Re-Ax Breathable Cover Layer

The REM-Fit 500 Ortho is an ideal choice for those who suffer from allergies. This is because the cover is hypoallergenic. Alongside this, the cover is easily removed and machine washable. This makes it a lot easier to keep the mattress clean and hygienic.

Besides this, the cover is made from a super soft material giving it a real luxury feel. In-built into the cover is Re-Ax fibres. These are thermo-regulating and help reduce the build-up of heat within the mattress. This allows you to keep cool throughout the night.

2. Cool Open-Cell Memory Foam Layer   

The first big layer of the mattress is a cool open-cell memory foam layer. The memory foam retains the traditional moulding feel that it has while removing the overheating issue. REM-Fit claims that the open-cell design allows this foam to be over thirty times more breathable than traditional memory foam. This adds comfort to the mattress whilst maintaining a healthy sleeping climate.

3. 2000 Full Sized Pocket Spring Layer

This layer is 2000 full-sized pocket springs. These are a much firmer gauge than is traditionally found in most mattresses. This provides an excellent level of support. Each spring within the mattress is individually encapsulated. This allows them to work independently of each other and with your body. 

They give the mattress great responsiveness and provide support quickly as you change sleeping positions. Another added benefit is that motion transfer across the mattress is minimised.

4. Edge-To-Edge Support Layer 

While not strictly the next layer of this mattress, it is an addition to this mattress that is worth mentioning. This layer of the mattress is foam sidewalls that surround the springs. These support the mattresses structure and prevent the springs from moving from side to side. This prevents them from being damaged and increases the stability of the mattress. 

Another great bonus of this feature is that edge support is massively increased. This means you can sleep right to the edge of the mattress without excess sagging or feeling as though you are going to roll off the mattress.

5. High-Density Foam Base Layer

The high-density foam base layer is a solid foundation layer for the mattress. This provides a good level of support for the other layers to sit upon. A good foundation layer increases the durability of the mattress and protects the springs from damage. REM-Fits confidence in this base shows with them offering a 15-year warranty with every purchase of the mattress.

Comfort, Support and Sleep Quality

The REM-Fit 500 Ortho mattress is the firmest option offered by REM-Fit. It is officially rated as a firm and is definitely on the upper end of this scale. On a 1-10 rating, it lands between a 7-8. When sleeping on the mattress there is a slight mould from the memory foam. The primary goal of this mattress is to provide support and have orthopaedic qualities. It does this very well.

How comfortable a mattress is can be widely different from person to person. Factors such as weight and sleeping position can greatly change how a mattress feels to sleep on. We have broken down each common sleeping position and examined what it will typically feel like to sleep on for an average person. This may differ from what is experienced personally.

If you are typically a back sleeper then you will be suited to the widest range of mattresses. The support and pressure relief from this mattress is top quality and will allow you to put your spine into a healthy position. If you are looking for a firmer mattress that will help ease potential backaches and pains then this could be a great choice for you.

Side sleepers generally require a slight sinkage to be able to position their hips properly for a good sleeping posture. If you are average or lighter in weight then this mattress may be too firm for this. You will not sink into the mattress much and so may not be able to get into a comfortable sleeping position. If this is the case then you may be better suited to the REM-Fit 400 or 600 Lux mattresses as they are much softer and allow you to sink into the mattress more.

Stomach sleepers need the most amount of support to sleep comfortably. Because this mattress is so firm, it does an excellent job of providing pressure relief and support. The hips and shoulders are well supported. If you sleep on your front then this could be a great option if you like a good firm mattress.

The mattresses added cooling features help prevent overheating during the night. While traditional memory foam has problems with breathability, the added spring layers and gel-infused memory foam increases airflow into the mattress and stops excess heat from developing. This mattress does a good job in terms of sleeping cool.

Motion Isolation is often an important trait for couples choosing a mattress. Considering this mattress is a hybrid, it does a relatively good job at minimising motion transfer. As the mattress is firmer the memory foam does well at minimising the bounce from the springs. As a result, this mattress will be a great fit if you are frequently disturbed by your partner’s movement during the night.

Edge support is one of this mattress’s strongest traits. The firm foam sidewalls are a great addition and prevent any excess sagging on the edges of the mattress. This allows you to sleep right up to the edges of the mattress and not feel as though you are going to roll off.

Trial and Guarantee

A 100-night trial is almost expected now with a bed in a box mattress. It is still more than appreciated and is a great bonus. This gives you time to try out the mattress and see if it suits you. If it doesn’t then return are a simple process. You can get in touch with the REM-Fit customer support team who will organise the free collection and a full refund. Another bonus is that all mattresses that are donated to the British Heart Foundation. 

An outstanding feature of ordering a mattress with REM-Fit is that all of their mattresses come with a 15-year guarantee. It is a decent amount better than the 10-year average. It shows REM-Fit’s confidence in their build quality in offering this.

With every order of the REM-Fit 500 Ortho mattress, they provide free next day delivery. This is great and much faster than the average offered by online mattress companies. Alternatively, if the next day delivery does not fit with your schedule then you can choose a delivery slot. These are all morning delivery slots and include Saturday morning.

The REM-Fit 500 Ortho is delivered in a small box, vacuum packaged and rolled. After removing its packaging it will take a few hours to expand to its normal size before being ready to use.

There may be some off-gassing when you first take this mattress out of the packaging. This is nothing to worry about and is very common with mattresses containing foam layers. It will dissipate within a few hours/days.

Some additional services that REM-Fit offer include old mattress removal. This does come with an additional charge, however. If you expect to have trouble moving the mattress into a room of your choice then REM-Fit offers a two-man delivery service who will deliver the mattress to a room of your choice. While helpful this will also come with an additional cost.
