[2026 Summer Bonus] 80% Feel 'Sleep Directly Impacts Productivity,' Yet Investment is Only 3.6%... Promoting 'Sleep Asset Investment' This Summer

Morght Inc. (Headquarters: Minato-ku, Tokyo; CEO: Kotoki Doi), operator of the sleep brand 'NELL,' conducted a survey on 'Summer Bonuses and Sleep Investment*' targeting 720 business professionals in their 30s and 40s.

The results revealed that the most common use for 2026 summer bonuses was 'savings/deposits (61.70%),' followed by 'asset management/investment (37.30%),' highlighting a strong interest in solid asset formation. Conversely, 'improving the sleep environment (3.60%)' ranked last. However, 79.8% of respondents acknowledged that 'sleep quality impacts work performance,' revealing a significant gap between the awareness of productivity improvement and actual investment behavior.

In response to these findings, NELL conducted its own research on the impact of mattresses on sleep quality and workplace productivity. Considering that sleep, which accounts for one-third of our lives (approx. 8 hours/day), is one of the most accessible and reliable forms of asset management, NELL proposes 'Sleep Asset Investment' as a new option for this summer's bonus.

Survey Summary - 'Defensive saving' and 'offensive investment' are the top two uses for bonuses, while 'sleep environment improvement' is only 3.6%. - Approximately 80% (79.8%) of professionals feel 'sleep quality impacts daytime performance and operational efficiency.' - Despite recognizing the importance of sleep, about 40% (39.2%) have taken no action to improve it. Even among those who feel it impacts their work, 1 in 4 (24.9%) do nothing. - On the other hand, more than half (56.6%) positively perceive spending on sleep environment improvements as a form of investment or asset formation.

Survey Details 1. Use of 2026 Summer Bonuses: 'Savings' and 'Asset Management' top the list. Sleep investment is just 3.6%. Respondents prioritized conservative spending, likely due to inflation and future uncertainty. Improving the sleep environment is currently under-prioritized.

2. The gap: 80% feel sleep impacts performance, but 40% take no action. Most understand the importance of sleep, but nearly half (39.2%) do nothing. This suggests a dilemma: they know it's important but don't know how to invest specifically.

3. Hidden new norm? Over half perceive 'Sleep environment improvement' as 'Investment/Asset formation.' Over 56.6% of respondents have viewed spending on mattresses and pillows as a form of asset formation. More professionals are viewing sleep not as 'consumption' but as 'self-investment' to boost daily productivity.

Effect of Pocket Coil Mattresses on Sleep and Productivity NELL conducted a participatory survey comparing the NELL Mattress (primarily pocket coils) to standard urethane mattresses. The results showed significant improvements in several sleep indicators for pocket coil mattresses, along with an increase in average workplace productivity scores. It is scientifically clear that changing the 'tool' of a mattress directly contributes to better daytime performance.

'Pocket Coil Mattress' enables 'Sleep Asset Formation' for approx. 30 JPY per day Using the NELL Mattress, which demonstrates higher average productivity, for 10 years results in a cost of approximately 30 JPY per day. This is about one-fifth the cost of a canned coffee (approx. 150 JPY) used to wake up during the day. This 'mattress investment' is arguably the easiest, high-return 'Sleep Asset Formation' strategy.

### Sleep Asset Cost Calculation - 109,000 JPY (Mattress price*) ÷ 3,650 days (10 years) ＝ Approx. 30 JPY per day - 'About one-fifth' of a canned coffee (approx. 150 JPY). No risk of principal loss, a 'most accessible asset management' with guaranteed returns every night. *For double size
