Twin mattress for Adults based on type

The numerous mattress companies and marketing gimmicks can make it confusing to make a decision. However, it just helps to be familiar with main types of mattresses as follows.

1. Polyurethane Foam – affordable option

Flexible Polyurethane Foam is the most extensively used kind of foam, considered low quality, not very durable but affordable with some that cost under $100. This foam is made of multifaceted alcohol called polyol that reacts with a petroleum byproduct called diisocyanate.

In mattresses, it could be used in combination with a top layer of memory foam or as a top layer in an innerspring mattress. Denser Polyurethane Foam mattresses are more durable but less dense than memory foam and latex.

As a base layer, its density could range from 1.5 to 3.0 pounds and as a top layer could be between 1.2 to 1.8 pounds.

Being comfy and support are important to consider while buying a mattress, it must be noted that while polyurethane Foam can provide for it, it mostly scores low on both aspects. Besides, while firmness is measured by Indentation Force Deflection for memory foam and latex, density is more important for polyurethane foam.

Is polyurethane foam safe to sleep on? While most polyurethane foam mattresses hold Certi-PUR-US certifications, the fact is that it is highly flammable and has to contain certain fire retardant chemicals.

These chemicals could possibly cause allergies, especially for kids. However, some mattresses could be mixed with wool that has natural flame retardant properties.

2. Twin mattress made of Memory foam – for comfort

Memory foam is not new and has been in the market for a long time. It is made of viscoelastic and also known as viscoelastic memory foam. This foam is known for its slow-motion quality when exerted with heat and pressure.

Although both polyurethane and memory foam are ‘open-cell’, the cells in memory foam are more elastic and fluid when acted upon.

Although memory foam can be supportive, it is, in fact, more slow-acting than latex and thus causing sleep interruptions. It, however, will not cause disturbance to a partner if you move. Being viscoelastic, it contributes to comfort by molding to body shapes and sizes.

Memory foam is recommended for people with aches and pains and it relieves pressure points on the body. These mattresses can sleep hot, soften, and sink more when temperatures rise. Innovations like gel foam added to the top layer of the mattress can make it cooler.

Denser memory foam is double the quality and more durable but can turn hot. Memory foam has the same Certi-PUR-US certification as polyurethane foam but is highly flammable and has to be treated with fire retardants.

It must be remembered that for the memory foam to provide full mattress support, it has to be combined with a base layer of polyurethane foam or innerspring. Memory foam is always more synonymous with comfort.

3. Latex – the durable option

Latex mattresses can be both synthetics as made from petrochemicals and natural from the sap of the rubber tree. Latex is fast-acting in comparison to memory foam thus provides deeper restful sleep.

It delivers better support and comfort and doesn’t sink in reaction to heat. Latex mattresses prices are higher than the other foam varieties.

These mattresses offer long-term durability of more than 20 years making them a worthwhile investment. The 2 types of latex Dunlop and Talalay varieties. The latter are air versions that promote breathability and sleeping cool.

Mattresses made of foam and latex typically need no box spring. A platform base, a plain box surface, or even a futon sofa is sufficient for these mattresses. Mattresses made of innerspring however typically need a box spring surface.

How to shop for the best adult twin mattress

Online tips – don’t get cheated while buying online

When shopping for a mattress online always make sure to do your homework and thoroughly run through different reviews and ratings. Check reviews for customer service reputation, top-rated mattresses and return policies.

A mattress that is very popular with a rating of 4 out of 5 stars is a safe bet. However, a cheap mattress could also offer the best value. Moreover, the ones that offer trial periods and better warranty options are better. Mattresses with video reviews may also give you a clearer picture.

Also, check if they allow a trial period. It is a great way to test out the mattress before buying.

Try it out

If you are physically present at a mattress outlet, you must lie on it and get a feel of it. Spend some time checking out various positions, toss and turn to understand if it could cause sleep disturbances.

Spend more time in the position you mostly sleep in at night. Check to see if a twin seems short and if you need the extra-long version. Ask the salespeople enough questions to clear doubts, look around and survey until you can narrow it down to a single favorite.

Check for Returns and warranties

Be sure of the return policies, the timeframe within which a mattress can be replaced of fully refunded and whether the company or outlet cover transportation costs.

While most mattresses offer warranties from 5 to 20 years, it doesn’t confirm the lifespan of the product. However, the ones with warranties of 20 years tend to go beyond the 5-year mark of lower quality mattresses. Some warranties also demand that you buy a combo box spring set for it to be valid.

Do your homework

If you prefer to go out and buy a mattress, start with research at home to decide on your personal preferences. Find stores that specialize in mattresses or have many brands like Sealy and Tempurpedic. Heavy people need more cushioning while lighter individuals could be comfortable with innerspring mattresses with medium firmness.

While comfort is a matter of personal choice, remember that medium-firm mattresses are better for back problems. Thickness can range from as thin as 4” to 6” and 10”. As a rule of thumb, mattresses that have a universal appeal have a plush feel but firmer support.

 Twin mattress for a heavy person

Heavy people on the lookout for a mattress that won’t cave in and to improve the quality of their sleep should consider their personal preferences and budget.

While companies make mattresses meant for heavy people, they’re not particularly targeting only heavy people.

If you’re above 200 pounds or the combined weight of you and your partner exceeds around 300 pounds, you would need a mattress that can support the pressure. Of top priority is a mattress made of quality material that can endure heavy weight on a regular basis.

Thickness is important to consider and for weight above 200 pounds, it is advisable to invest in a mattress not less than 10” inches thick. A thicker mattress can support deeper compression, thus improving the quality of sleep and minimizing aches and pains.

Firmness has to be accounted for, as a softer product is likely to cause an indentation in the case of heavyweight. It must be noted that a large people above 200 pounds may experience a mattress to be medium firm when it is normally measured to be firm or extra firm.

Heavier people may also need a mattress that doesn’t trap heat. Eventually, it’s best to focus on support, comfort, durability, and budget while choosing a mattress.

Twin v/s double mattresses – choose carefully

Choosing between twin and double size mattress will depend on your needs and whether you’re a solo sleeper. Twin mattresses are meant to have the least space universally and suitable for one person. Twin mattresses are therefore convenient for dorm rooms, day beds or guest beds.

A couple choosing a double mattress arrangement for their home should remember that it would only afford them around 25” of space across. This squeeze fit could turn out to be bumpy at night or end up in one person falling off the bed.

A twin size may also offer less space for a single person breadthwise but could be a solution for space constraints. A full or double mattress is ideal for a single person providing a comfortable 50” to stretch out. While a double XL mattress provides for ample space for a taller person.

The design and weight of a folding mattress should allow for easy storage and mobility. Some have 2 panels that fold in the middle while some have 3 panels that fold in 2 places. Some also have straps that can be attached to hang the mattress while stored away.
